I recently helped the local Boy Scouts club source a wireless router and modem and install it. After a bunch of research, I concluded the best value was with either a Netgear DG834G or a 3Com Office Connect 3CRWDR101A-75. After several failed bids I finally managed to grab a DG834G on ebay for only £32. It's a version 2 rather than a version 3 which is a little unfortunate. The main difference is RHOS compliance although I hope that they will still be providing firmware upgrades for version 2.
