I use RBI racks and don't plan on going any other route. I'm sure all the other racks out there are perfectly fine but Rich is just an awesome guy to work with and will do his best to accommodate whatever you need. I'll pay more for good quality, I'll pay more and keep coming back for great service. Just placed another order last Friday actually.
And there are a lot of options for make-shift pedestals. Target has wood cubes rated for 200 pounds each that work really well. If you ask, Rich can probably also fab something up for you for that as well (for a price of course).
