This is definitely the route I'd go.  I'm a BIG fan of the Buffalo 
wireless access points if they've re-entered the channel near you (a 
patent troll prevented their sale for the last 18 months, but that court 
case was just overturned), as they support DD-WRT.  Failing that, the 
Linksys WRT54GL isn't a half bad unit.

Custom firmware (dd-wrt, OpenWRT, Tomato) also give you a lot finer 
grained control over what happens on the AP.
