I'm going to order a Grizzly BS. I'm looking at the G0555 & G0555X. I like the extra power of the X but it's a single speed. Am I truley giving up anything by only getting the single speed over the two speed of the non-X? I plan to add the riser and do some re-sawing so I thought the extra power would be nice. I would rather have the power and not need it then not have it and need it.
