Get IOS FireWall Feauture set, router with the 2 LAN and 2 WAN 
interfaces, and say _get away_ to the hw vendors.

No doubt, it's possible to enter into IOS if you did not installed access 
lists on the VTY, keep working some extra services (such as router-based 
WWW) or so on; but it do not depend of the firewalls at all... And - if 
you don't need session-level firewall (with the analysing of SMTP content 
for example) IOS FW feature set is very effective solution.
