Most Favorable Review

good cheap video card

EVGA 02G-P4-2643-RX GeForce GT 640 2GB 128-Bit DDR3 PCI Express 3.0 x16 HDCP Ready Video Card Certified Refurbished
EVGA 02G-P4-2643-RX GeForce GT 640 2GB 128-Bit DDR3 PCI Express 3.0 x16 HDCP Ready Video Card Certified Refurbished

Pros: inexpensive lower-mid range Geforce card. dual DVI is exactly what I needed to run my dual monitors GT640 doesn't require any aux power connections. plenty fast for google earth, stellarium, and simple 3D modeling software.

Cons: just OK for basic gaming at moderate resolutions. thats OK, I don't game.

Overall Review: this is at least twice as fast as the onboard HD4000 on my Core i5-3570K, but more important, turning off the HD4000 speeds up my CPU. With it off, my CPU is rock stable at 4.2Ghz, so using this board is a win-win.

awful lens

Opteka 85mm F/1.8 Manual Focus Aspherical Medium Telephoto Lens
Opteka 85mm F/1.8 Manual Focus Aspherical Medium Telephoto Lens

Pros: cheap.

Cons: really cheap. I was sort of hoping 2013 China could make a lens as good as 1966 Japan. Dream on. wide open this lens is total mush with ghosting. you need to stop down about 2 stops before the blur gets even remotely OK. ugly bokeh. one of the reasons for a fast portait lens is to achieve shallow depth of field. the focus is far rougher than my 1960s pentax thread-on M42 lenses. the iris only has whole stops, and not even ones, f/ 1.8, 2.5, 3.2, 4, 5, 7, 11, 22. the iris is rough to turn too. the exterior finish of the metal is pebbly rather than satin. the lens hood is an integral part of the lens, the lenscap fits on the hood not the lens. I'm not sure you can use a filter with this. there is a fair amount of purple ghosts on contrasty edges off center... this is chromatic abberation, far more than I'd expect on an APS-C camera with a 85mm lens.

Overall Review: I got this lens to do wide field astrophotography, and still lifes. I haven't tried it yet on the night sky, the full moon had too much glare last night

nice laptop

Dell Latitude E6420 Intel i5 2500MHz 250Gig HDD 8192mb DVD ROM 14.0” WideScreen LCD Windows 7 Professional 64 Bit Laptop Notebook
Dell Latitude E6420 Intel i5 2500MHz 250Gig HDD 8192mb DVD ROM 14.0” WideScreen LCD Windows 7 Professional 64 Bit Laptop Notebook

Pros: Excellent business grade laptop. The one I got had the HD+ screen, 1600x900! I was ready to buy and swap one in of these... I swapped the slow 250GB HD for a Crucial MX100 512GB SSD, and this lappie is /zippie/. Backlit keyboard is a nice bonus.

Cons: It's a bit heavier than 14" consumer class laptops, but its metal, and made to last.

Brown Key version

Cherry MX-Board 3.0 Keyboard
Cherry MX-Board 3.0 Keyboard

Pros: I ordered this keyboard from newegg via fleabay, where it DID have the full part number, G80-3850LXBEU-2 ... The listing here on Newegg's site only says MX Board 3.0 3850, but theres 4 different versions of the G80-3850, with 4 different types of MX keys, red (short throw linear), brown (soft tactile), blue (clicky tactile) and black (high force linear). This IS the brown key version, which for this old touch typer has the perfect feel. FAST typing, very positive. Classic 104 key layout. you can disable the Windows keys if, like me, you find them an annoyance.

Cons: the keys are a little noiser than I would have liked when I bottom them out, so I've ordered a bag of the red o-ring silencers for them. I wish they'd just sell the keyboard with them preinstalled.

works

Koutech IO-RCM632 USB 3.0 Support SD/ CF/ xD/ MS/ MMC. Multi-in-1 SuperSpeed USB 3.0 Front Panel Internal Card Reader with USB 3.0 Port (3.5")
Koutech IO-RCM632 USB 3.0 Support SD/ CF/ xD/ MS/ MMC. Multi-in-1 SuperSpeed USB 3.0 Front Panel Internal Card Reader with USB 3.0 Port (3.5")

Pros: this one seems to work OK. I've only tested usb sticks and SD cards in it, but the similar usb3 all-in-1 I got a year ago never worked right.

Cons: it would be very cool if there was a soft amber or green led inside this so the slots were backlit so I can tell where to plug stuff in my black case under my desk when the room lights are low. I'm thinking of modding mine.

went bad...

G.SKILL 32GB microSDHC Flash Card w/ SD Adapter Model FF-TSDG32GA-C6
G.SKILL 32GB microSDHC Flash Card w/ SD Adapter Model FF-TSDG32GA-C6

Pros: it worked for a few weeks

Cons: got flakey, then stopped working entirely, tested in several devices.

Overall Review: meh. sticking with SanDisk Ultra from now on. not worth the hassle of dealing with flakey flash. I got this for my daughter's android phone, and she lost all the pictures she'd put on it, and now it won't even format or mount, its dead.
