Suggestion on WLAN setup

Hello Friends,

I need your suggestion on WAP to use in office while implementing WLAN. I have tried Cisco 1200 Aironets before for public wireless but things I want to implement in WLAN are totally missing in these Aironets. Thats why I need your help, so please suggest me.

I need WAP which has following features:
1. 802.11 a/b/g compatible
2. Good Encryption (encryption which can be applied without additional
hardware like WPA-PSK or something you can suggest.
3. MAC address filter
4. No SSID broadcast
5. Monitoring if possible

Thanks in advance.
