I bought my engine stand at Harbor Freight and am satisfied with it. The Cherry picker came from Costco some seven years ago and does it's job well but if I had to do it over again, I'd buy the ones that fold up/down so I can store it in the corner. Mine takes alot of storage space but I guess I can dissassemble them when in not in use.
I see Summit sell each that folds up. Cherry picker at $200 and the engine stand at $120.

As for compressor, I'd suggest the biggest you can get. I've used a Sears 5 hp 20 gal vertical tank for years but when using a grinder or the chisel, it seem to overwork the motor. I just bought a Cambell Hausfeld 6.5 HP 60 gal. 220v ertical. A middle of the road brand but affordable.
