I've been using the EnGenius ECB9500 wireless access point quite a bit. It has a lot going for it: small in size, power-over-ethernet, low cost.
One thing that has been a thorn in my side is that up til now, SNMP monitoring has been difficult because the built-in firewall rejects packets that are not from the same subnet that the IP of the WAP is on. Naturally my monitoring lives in the server room which is on a different subnet.
The firmware changelog notes that this was fixed in 2.3.0: Read more... about EnGenius ECB9500 firmware 2.3.3 enables SNMP monitoring
