Good luck; they're fairly rare. From what I can tell, Cisco only
supports jumbo frames on the Catalyst 5000 and 6000 families. Extreme
supports them on at least a few models. The cheapest jumbo frame
switch that I could find is the Intel 480T, which is over $7,000.

After doing a bunch of benchmarking, for our hardware and workload,
jumbo frames don't really seem to help performance much anyway, so I
ended up getting a $1,300 Dell 5012 (10 10/100/1000, 2 GBIC) switch.

I've heard rumors that Asante will have a jumbo-capable switch in May
or so. Since they seem to OEM the same hardware that Dell does (for 3x
Dell's cost), I wouldn't be too suprised to see a $1,500 16-port gig
switch from Dell in a few months.
