Have you looked into an Airport Express base station? I have one at college and I enjoy it - it also functions as a print server and you can do streaming audio from itunes. I have had a couple Linksys routers, and they tend to function well with firmware updates - I have generally had issues out of the box, but it's been over 2 years since I bought my WRT54g so hopefully they've improved
. However, I would definitely recommend linksys over belkin or netgear, I have known people with very odd config problems.
The only reason I have ever considered buying an Airport base station is that the Airport Express units can be set up in a WDS (Wireless Distribution System) to extend network range, but as the 802.11n draft is coming into use, that hardly seems like a useful feature anymore
. Hopefully apple will jump on the wireless-N bandwagon.
