As long as you're not doing anything too fancy on the routing front, 
the 3750's are a good solution for this. Given that the ports are 
slightly oversubscribed on some models (as I understand it) just make 
sure your devices aren't in the same group of four ports and you 
should be fine...

The 2851 will max out (according to cisco) at around 112 Mb/s while 
the 3845 will go to 256 Mb/s. So, well short of gigabit speeds. And 
that's assuming you're not doing anything other than routing. YMMV. 
For reference, there is a gig HWIC (HWIC-1GE-SFP) but I seriously 
doubt you'll get anything close to gigabit out of it. Not sure of the 
inherent limitations of a HWIC slot.
