We are about to put a firewall into out network to replace an existing one.  We have a Cisco 2620 and are trying to decide whether to upgrade the 2620 with memory and the bios and put the Cisco Firewall package onto it or get a PIX 506.  

Does anyone have any suggestions for either?  Downsides/upsides?

Personal preference, but the PIX was built ground up as a firewall, and does it very well. 2620 was designed as a router, and does it very well. Putting the firewall feature set on top of the router still does not get you the full capabilities of the PIX appliance.
How many users do you have? If more than 50, I would seriously consider the 515E Restricted.

Here is  my  2cents worth.

Let the router do routing, and the firewall do firewalling and vpn stuff.

The pix 506 only has 10mb interfaces, and your 2620 will have 100mb interfaces.  Have you considered a  515, they
also more scalabe and can have hardware vpn acceleration cards installed, also you could go bigger and implement a dmz.

The 506 is a really good remote point builder but for your
central hub, it is limited.



I would recommend a 515 or a 535 if you have the budget, but if you can only afford the 506 it is better than nothing.

We have right at 50 users on our network at the moment.

If your budget will permit, go with the 515. It is expandable to add a DMZ interface, is much more powerful than the 506, and you can add a failover firewall in the future if you need it. The 506 is a set configuration. You can take advantage of the VPN capabilities of the PIX also to set it up as a VPN termination for IPSEC and/or PPTP VPN connections.
Suggestion. To provide a more complete security package, be sure to enable logging to a syslog server for both the screening router, and the firewall.
