Integrating 3Com & Cisco for VLANs

We have several 3Com Superstack II 3300 switches.

We're interested in running VLANs within the fabric, and the 3Coms can do 802.1Q.

Can anyone suggest a low-cost Cisco router which would reliably route between VLANs on the 3Coms? I won't mind if I end up with extra Ethernet ports (e.g., one suggestion made to me was a 2948G-L3, although the price was a little higher than I want to pay).

Thanks.
