I agree with Jesse, a mobile base under a top heavy DP is asking for trouble.
If you're looking for a good solid machine for a reasonable price you might want to look into the Rigid. Nice price and a lifetime warranty. I recently purchased the Rikon and was very disapointed to find out the massive 3/4" chuck can't hold anything smaller than 1/4" - so now I have the floor model AND a bench top.
