I have one of their $9.99 HVLP spray guns. IF (emphasize the word greatly) you take it completely apart, clean it of all bits, dirt and leavings from machining, etc, polish all needles, jets, etc and put it back together correctly (check to be sure o-rings weren't forgotten when it was made) and if you clean it well after every use and pay close attention to your adjustments it isn't a bad spray gun. Good to adjust and use for narrow items, wheels, etc where you need a small pattern. Now to claim this is an actual HVLP gun...well, no you'll have to spend more to get one of those but it is certainly worth $10.80 (sales tax included).
As for the socket pieces...if you aren't using much torque, they're ok. Otherwise, you might get to buy some others.
Engine stand...use common sense with that thing. Especially if you are rotating an engine. This stand was not designed for long inline sixes, by the way. I made a heavy wood support for the outbound end when working with a 235. Also modify the rear attaching part so that you can connect with the 235 better.
Engine hoist...use common sense and remove your engine after you pull it. There are hoists on which it is fine to leave an engine suspended. This isn't one of them.
