Best Business Router(s) - 2 ADSL lines / up to 20 users

At the office, we have 2 ADSL lines and to each line, we want around 8-10 internet connections. We already have 2 HP switches (30 connections each I think) so I need a router solution between the ADSL modems and the switches.

I was looking at 2 options.

1. LINKSYS 10/100 8-PORT VPN ROUTER - connect both ADSL lines to this and connect a switch to each port and the wireless access point to another port.

2. NETGEAR PROSAFE GIGABIT VPN FIREWALL ROUTER - get 2 of these and connect each one to their own switch and divide the users by client (2 clients).

We run VPN for 1 client only.

Any advice on the above or are my choices ill-informed?

Id recommend SonicWALL, 7 layer firewall etc. We use one at our business/home here, works well once its setup.
