Jet Performax
I've had a Jet Performax 2244 drum sander for about 5 years now. Good machine but larger than I wanted at first. ( I wanted a smaller unit, but got an incredible deal from a local supplier that was downsizing )
Jet is long time owned by WMH holding and has quality products. They bought the "Performax" name a number of years back, hence the name Jet Performax.
I use mine for veneer thicknessing typically on QSWO for Craftsman / Greene & Greene table legs where I want to see the ray flecks on all faces of the legs. The machine will easily sand to less than 0.060" and is well built. It also is available in smaller sizes 16-32, 10-20, but I have no experience with them. I have not heard any bad things about the Grizzly units.
Depending on what you want to do with this kind of tool it can be very handy or a PITA. They are not a substitute for thickness planers, but do their intended jobs well.
Feel free to PM me and I can share more experiences if it would help.
