My two cents: That's a really good price for those cabinets.
To clean the grill cloth, get some Tuff Stuff (made by Simonize) at an auto parts store. If you leave the cloth on the frame, spray it on VERY LIGHTLY and wipe off with a towel. However, the best way to do it is to take the cloth completely off the frames (pull all the staples out first), spray on the Tuff Stuff, scrub it with a nylon brush, then blast it with COLD water at a car wash or use a pressure washer if you have one at home. (Hot water will shrink the cloth, creating new problems, so don't do that.) It takes a lot of patience to get the cloth back on the frame straight and taut but the result is worth it.
