Catalyst 3500 series XL and most Catalyst 2900 series XL switches support a total of 250 VLANs and 64 spanning-tree instances. The Catalyst 2912 XL, 2924 XL, and 2924C XL switches support a total of 64 VLANs and 64 spanning-tree instances. Regardless of the switch model, only 64 spanning-tree instances are supported.
i believe if you exceed the 64 vlan, the vlan database will not get updated and the switch will just give you errors but will not crash the switch.
i say dont take any shortcuts and do something properly now and you dont have to change anthing in the future. i suggest you go for at least the 2960's. we uses the 2960 switches for this type of setup. you get Up to 255 VLANs per switch and up to 128 spanning-tree instances per switch are supported.
