Communicate from a laptop

Sorry for being a little off topic but I think this does affect more and 
more people sending sensitive data on AS/400's all the time.

I am looking for suggestions on a router that will be a VPN end point 
over wireless.
Wireless laptop --> router.  

I have been running into more and more people that are 
communicating sensitive data over wireless with either no security 
or wep/wpa which is easily cracked.  I'm looking for a router under 
$500.00.  I'm not looking for a solution that uses the AS/400 as an 
end point.  A lot of people need to communicate to an AS/400 and 
need to use the same connection to communicate to the internet.

I know there is a SonicWall TZW available and a Netgear FVM318 
which is no longer in production that has this capability.  I'm 
wondering if anyone knows of any other routers that will do iPSec 
VPN.

Thank you,
