I tried a search and didn't really come up with the specific answer I was looking for. Everyone seems to be on the same page that the EVC Ez's are the way to go, but is one better than the other? When looking at the price comparison of a new EZ2 going for around 400 dollars vs a working, but used EZ unit coming in around 250, is it worth spending the extra money on a new one? I'm not really too concerned about the low/high settings on the 2, where as the pros for a new never used unit are up really something to take into consideration. Hoping you could help me out. Thanks for the space.
