The WISP I work with uses WRT54GL. Commonly available, already got the solder points arranged neatly in 2x5 for serial and 2x6 for JTAG ready for an easy solder-job to add the connectors. Simple 12-Volt power supply that is commonly available, and is very flexible on voltage it will accept from 7V up to 20V at least. Very good if you are doing simple passive PoE like I have done, where voltage may drop over an ethernet cable but in this case the WRT is forgiving of that. Power consumption about 5 Watts.
I have a Buffalo unit also to play with, but have to say it's inferior on all the points I just mentioned. I'm not sure what the original poster's motivation is but I don't like to CHEAP OUT too much and have to do a lot of fiddling with hardware after installation. The GL is very temperature resistant also, I stick a simple aluminum ramsink on the CPU and have them in attics and outdoor enclosures in Georgia summertime no heat-related hardware problems so far. I did have a wasp-nest problem inside one enclosure where I hadn't sealed an entry point well enough.
I have used cheaper D-Link and SMC AP's in earlier years, and MY GOD you have no idea how annoying it is to get access to and climb up to replace a failed unit. Especially those dadgum D-Links every single one of them blew out within a year. Time is money and I spent way more in manhours FIXING the problem than I ever saved by shaving a couple of bucks off the original hardware, all of which I ended up replacing with GL units.
