Currently I have a few 3com access points. We employ radius authentication based on the mac address of the client. Every few days the 3com's seem to lock up and need a restart. I have some experience with cisco AP's but I'm looking for any alternatives in the $200-$400 range for some decent business grade access points. We're not talking hundreds of clients, probably a dozen per AP with a total of 6-8 AP's spread around for roaming access.
