Wireless networking security appliances?

["Mark G. Spencer" <mspencer () evidentdata com>]

I'm looking for thoughts on wireless networking security appliances.  If you have evaluated and/or implemented these 
devices, what do you think about them in terms of cost, installation, maintenance, and effectiveness?

One question I have is if you have implemented some kind of security already on your wireless network (e.g. using a 
SonicWALL TZW w/ IPSec tunnels setup for all wireless clients) would you consider other wireless security appliances as 
well?  I see that some of the vendors hawk intrusion detection features.

And finally .. are there any good reviews in magazines or online of all these products you would recommend?  

Thanks,

Mark
