LINKSYS PLEK400 Powerline AV 1-Port Network Adapter Kit Up to 200Mbps

Pros: Really couldn't be any easier to setup; works exactly as it should, without any problems so far. The price is comparatively pretty good, as well.

Cons: None

Other Thoughts: Bought to use with gaming console far away from router, works much more reliably than wireless connection.

Pros: No brainer on connection even a grade schooler can get things connected.
Takes advantage of existing household wiring so no need to run ethernet cable.
Using this to get video data from outside webcams to my server and it works great.
Going to order another set to see if VOIP will work on a piggy backed router.

Cons: Absolutely none.

Other Thoughts: Oh and do not attempt to plug this into a UPS supply or a cheap surge suppressor it won't work if you do for obvious reasons.

Pros: Plug and Play

Cons: Cost is about the same as buying a SOHO wireless router.

Other Thoughts: I bought this kit to attempt to get better speed to my sons room. Our wireless access point is on the first floor while his bedroom is on the third. Thus the wireless signal wasn't the best. With the power line adapters we are getting a solid 30Mbps. Whereas the wireless access point would fluctuate dramatically. Not peak performance, but not bad for traversing one circuit, into the breaker box, and then up the run to the third floor.

So I say again... Not bad.
