LOVE my new Jet 1221VS...
I have to admit, I've never used the Delta 460, but I find that I love my new Jet 1221VS more each time I turn a project on it!!! It's heavy, steady and very smooth running! I just finished a small 5" Sasafras Vessel on it this afternoon and really appreciated the VS feature... I can slow the speed down to sand, apply sealer and then speed up to apply finish. It's range of speeds even when running on the middle pulley is wonderful and so far I haven't had to change pulley positions to turn hollow or smooth finish anything yet. Love the safer position of the on/off, speed and reverse switch...out of the range of fire and nice bright digital readout! My ONLY complaint is the same as several others, for the price (definitely buy it on sale w/free shipping!!!) the paint should be 'powder coated' but once I wear the paint off the bed rails, I'll repaint to keep it sparkling! ;>) Needless to say, I can't say enough nice things to say about the JET 1221VS!!!!
