If you are looking for the full, I may have an alternative for you. I have been field testing a power arm alternative, the Hydra-Positioner, for the last month or so. It is made here in Minnesota by a young man in a local machine shop. His grandfather used to make and sell them in the 70s/80's. He was a carver and so is his grandson. They did a production run of 20 recently and dad said he doesn't get to make any more or advertise until these sell. They are a fully hydraulic activated vise similar to the Wilton at about 1/2 the price. What I also like is that they can be serviced (Replace orings, fill hydraulic fluid level) by the carver, or sent back if you crank hard enough to blow a seal. About 6 of us in the MN decoy carving club bought them recently and a few have gone on ebay. One of our members has one he bought from grandpa years ago and says it is still ticking. The price is $200.00 plus $15 shipping. I planned to post some pictures tomorrow, but found a picture thread from Doug Muldowney on his website here.

The phone is not often manned, but when it is, its their aunt. Tell Brad, Steve Froelich refered you. I don't get anything but I am trying to help him get going. Its like an extension of my Junior Achievement mentoring. I think he has a great product and its priced right.
