Be warned that in a lot of areas wireless is nearly impossible to maintain w/o it dropping constantly. I live in an area that is very close to a radio station/tower and for about four hours in the morning it will completely disrupt my wireless connection and screw up my cordless phones. If you want convenience, you could go with a wired+wireless combo router just in case you have problems with wireless in your area at certain times during the day.
At work we needed a small setup for wireless, we went with Buffalo's WHR-HP-G54 Turbo G unit. It was fairly cheap, cost us around $70.00 and hasn't lost sync yet. At my home though almost all pure wireless systems will fail
