You get sturdy and durable hydraulic barber chairs between $100-$150.

This is difficult to believe, given that new cheap office/task chairs start at that price. Do you have a link?

These are the sort that I see in most barber shops, and are in that price-range: http://www.bestmassagesalon.com/product_p/pro3.htm

They probably wouldn't make a good drop-in replacement for office chairs since they aren't on wheels. On the other hand, footrests are nice...
