We've long used the Linksys WAP54G AP....for residential applications it works very well. Combined with their power over ethernet injector, the device can be placed just about anywhere (we like to locate them in centrally located closets on the second floor). No high voltage necessary with the use of the PPOE device.
[Link: linksys.com]Down at the head end we've been using their BEFSR41 router along with a Custom RSH shelf from Middle Atlantic for neat mounting in a 19" wall rack. We also use their rack mount 10/100 16 port switch (EF4116) for most of our installs.
