heres a tip-COWEN is going to put a uncapper on the market similar to there handy man uncapper-but the new one-you dont crank it-and the price is at $1900 -comes out in may -if you are going to spend money in that ballpark buy something
that you can grow with-as far as the uncapper you ask about -i know a guy that has one and he says it is ok-of course after spending the money for it and paying freight-(only ships freight) he is not about to admit that it is just a toy-you can Email cowen or call them-and talk about what the new unit is all about -if you need a link let me know
