Pros: runs DD-WRT (micro) semi-straightforward to install DD-WRT inexpensive small / light (good for travel router) makes a *really* inexpensive bridge

Cons: stock antenna not as good as the one that came on the 'U' version of this router. Current version of the firmware needs to be dropped back to an earlier version in order to flash DD-WRT

Overall Review: 1) go to asus.com - get 2.0.0.8 or earlier. 2) rename the "version" part of the filename to be something larger than whatever's currently on your new router 3) firmware update, pointing at the "looks like newer" firmware 4) firmware update, using dd-wrt micro (no need to use the special for-asus TRW file) 5) setup dd-wrt

Pros: Worked at USB 3.0 speeds. Compact flash slot problem-free

Cons: Stopped working after two or three months - for a while it would work but the motherboard couldn't boot with it plugged in (internal plug on mboard) but would work if you plugged it in after boot. Now it doesn't work at all. Very light usage (read CF card maybe 10 times, micro SD twice).

Overall Review: I might consider another one of these if it was free, but otherwise it's just not worth my trouble, not to mention money.

Pros: Worked great that first time. Includes motherboard header plug

Cons: The second time I tried to copy images off a CF card, it can show file contents but copies 'hang'.

Overall Review: If you need a single use device, this'll be great, otherwise not so much. Newegg return policy is that they muse receive the item before 30 days are up. Purchased on 9/29, today is 10/29, so a throwaway item. Not sure I'd want a replacement anyway.

Pros: Cheap Probably works with lots of other cards

Cons: Does not work with 4G SD cards (note I have not tested with HDSD, just SD). Fits in the space for a floppy drive just fine

Pros: small, wall mountable, metal case, separate grounding screw, still faster than most people's DSL connection, so fine if you were just looking to add a few ports to the firewall you got along with your DSL account

Cons: both slow (10T) and a hub rather than a switch (analog amp vs digital packet forwarding)

Overall Review: If you have any really long runs of CAT5 and are having problems running at 100TX, try sticking one of these between teh switch on one side and the long line itself. This will force speed negotiation down to 10T - which may actually better than you're getting with an (attempted) 100Tx that's having a lot of faied packets / re-sends. I carry one of these around in my bag so I can "vamp" onto a line and use ethereal when trying to diagnose a network problem at a site. Probably should replace it with a 10/100 hub before those all become obsolete as well.
