Anyone have recommendations on decent quality and reasonably priced mobility bases for table saws?

I haven't paid any attention to the market in years, googled yesterday and was a little shocked at the prices I saw. Last I remember, they were half of what I'm seeing now. Bases for would cost more than the saws. Two tablesaws unexpectedly followed me home this last week, a nice Delta contractor with Biesmeyer just like my first saw was, and a big old Unisaw with all the Biesmeyer stuff that I always thought I really wanted. I need neither but for nostalgia. Need them on bases so I can move them out of the way when I'm making money, not just playing.
