It really depends on the topology of the network you are planning. L3 really comes in handy if you are doing a lot of inter-VLAN switching as it reduces load and the extra hops to go up to the router and back down to the switch.

The lowest model of switch with Layer-3 capability is Catalyst 3560. Out-of-the-box, these series support basic Layer-3 (static routing and RIP), or you can upgrade the s/w to enhanced layer-3 (EIGRP, OSPF, BGP).
