I guess I did not state why the two ISP's. It was not for separating originally. Our current T1 has a 5 year contract (not my choice, signed the month before I started). To increase bandwidth was insane cost. So I added second line, cable with 15 down 2 up, for increased bandwidth (do not need the up speed). After some investigation, I am going with a Radware Load balancer. This comes after the two modems, before firewall. Firewall will act as DHCP (we only have approx. 80 computers). Thanks for the help. (If my idea is a nightmare, other ideas appreciated)
