Thanks to all who responded to my earlier post. I'm down to two -- the Nova DVR XP and the Nova 1624-44. The advantages of the XP, as I read the specs, are the EVS and the larger HP motor. So ... how much difference does 1/4 HP make in the real world? Are speed changes relatively easy on the 1624? There's about a $600 difference in play here. If changing speeds on the 1624 is a real PITA and the extra 1/4 HP is significant, I will go for the DVR. If not, I'll use the difference for some other toys.
