Oh God, I hate the most ugly Cisco compatibility matrix. What a horror  
show! It's like a big crap shoot picking a firmware image!

I actually like the Dell Powerconnects. They are solid performers and  
offer switches of all capabilites.

A 48 port Gbe layer 3 managed (web and cli) powerconnect with PoE on  
all 48 ports (not 24 out of the 48 like some similar Ciscos) goes for  
around $2000 a comparable Cisco one goes for around $3800.
