it really have a cost impact and does not bring you heaps. gig over coper works
properly.
I'd put a L3 switch to aggregate all your distribution switches, or a regular switch
with multiple coper gig ports and then a router attached with a trunk to do intervlan
routing. L3 switching really give you a pretty good boost however.
All of this depends on the budget you want to put in.
Another good thing to do is to try to get the same brand for the lot, it helps for
software upgrade
and may give you interesting additional features (like global QoS etc..). Brands, i'd
go
cisco, but price is often an issue and we can't say they 're cheap.
