Roller jacks.....

You're right about the POS casters on the Harbor Freight ones. The Craftsman has the steam roller aluminum front, works good, the rear casters aren't aluminum and seem to hold nice. They have yet to come loose.

This Craftsman one is a nice niche. I somehow end up bringing it everywhere, so aluminum is ideal for me. If I only found myself working in the garage at the house, I would have picked up a Blackhawk or something like you just got. Nothing beats the reliability of a steel jack with a wide frame.

This Craftsman one has a wide frame and a wide face, along with the speed arm and light weight, so it appealed to me over the other aluminum ones out there that were less expensive. I think I paid $200 for it? It's certainly paid for itself, though. I would have saved money on a steel one, but I'm always hauling it around. Quick release and detent ball break down handle is nice. Doesn't seem to wobble around like the Harbor freight ones do, but if I had my way, everything would be at home with a steel one or a lift... Yeah. Right.
