Cisco ASA-5505 or Netgear FVX538 (or other?)

Hi.
I’m currently looking for a new firewall to replace my old PIX501. I do not need many VPN clients (about 3-4 clients), so VPN users/VPN throughput is not an issue.

My current PIX501 has worked fine for several years, but I think it’s time to upgrade to a firewall with todays new security features.

Does anyone have any experience with these firewalls?
Pros/cons?
Other suggestions?

Thanks!
