RE: bow workbench ?
Harvestor - are you talking about a workbench or a bow vice? Or are you looking for an inexpensive bow Press?
All 3 are different animals. As for bow press I wouldn't recommend you even consider "cheap". I know I wouldn't want a $700 bow sitting in something that was cheap!
If you are talking about a bench or vice you can go inexpensive. As for a bench I got these plastic corner frames and build my own out of 2X4's and a sheet of plywood. No drawers but very stable and for the size I couldn't beat the $60 price tag. Mine came with a plastic vice that attaches to it, but I haven't tried it out so can't recommend for holding a bow.
If you want info on the bench kit, PM me and I'll find the website for ya.
