The unipro I have works fine. One thing that is different on that one(your link), the lock/clasp thing looks much better than the one I have. Need a flipping wrinch to adjust the handle, total pain.
A while back I was trying to find the lightest 175.
Disappointingly, almost all 17 inch machines are 90-100 pounds.
The only I found lighter was this one at 82 pounds, which is probably mostly due to the roto-molded apron.
