I'm looking to upgrade my table saw. Currently I am using one of the Dewalt contractor saws (#7480). My biggest complaint is that the mitre slots are not very even so my Incra mitre gauge does not move smoothly from start to finish and my crosscut sled has a bit of side to side movement so it doesn't cut 90 deg all the time. As much as I would like a proper cabinet saw it is not in the budget right now, so I am looking at the Rigid 4520 saw. Anyone have one of these and could comment on the mitre slots/overall opinions of the saw? Also any other options out there in the $500 range?
