I see how cat6 works for economics of scale; but when I last year looked to price 10gbs switches for a lan for a school (with a meagre budget) - I was surprised at how expensive second hand 10gps gear was. In the end we stayed with 1gbps even though we had some use-cases where 10gbps would make sense; mostly budget San/nas for video edit/backup. And to a lesser degree audio editing. I think the 1gbps Cisco switches were hand-me-downs from a university - but I saw no indication of reasonably priced 10gbps switches with minimal management (we didn't need "all" of Cisco ios - but minimal remote management and steady performance would be nice). We also threw some lan parties, so budget soho stuff that'd fall over easily wasn't really an option.
