I just did about 15 of these, they have a lot plastic, but the steel frame is a good solid piece. Then there are the steel rods that have rubber rollers on them. The rods look like stainless, but they aren't. These where HPs, I tried to sell the ink cartridges, but I guess they are too common, only got an offer of $.50 each. Oh well, still got more scrap $ than what I paid for them.
