I think you've already solved your problem. You don't need Cisco. You'd be 
paying your dollars to their marketing and advertising people instead of the 

I had looked at performance comparisons of switches when we were to buy one 
and I ended up with a 3com switch (which wasn't the cheapest). You'd need 
something like that, don't trust what the companies themselves claim about 
the performance of the switches.

I would recommend the switch we bought, but since there should be new models 
around you would need to see the price/performance for yourself. Did you 
search the web for any performance study?
