I have the QuickJack BL-7000SLX that I bought Feb 2019 for $1295. In short, I love them. Only complaint is that they are heavy and not super easy to move around and get out of the way.
I've used them for lots of things from simple oil change and tire rotations, transmission swaps, work on my UTV and ZT mower. Also used it for donor disassembly. I've not had my goblin on them yet though, but shouldn't be a problem to do so. Lowest car I've ever had on mine was a 1996 300ZX and didn't have issue.
Also worth mentioning that I've left vehicles in the air on the QJ for 2 months at a time, never been an issue. My 7000SLX model has 2 locking positions so raise it all the way, set the lock, lower until it locks and release pressure on pump. Disconnect the pump/hoses and the car is securely in the air on the QJ for as long as you need, no reliance on hydraulics to keep it up.
Some random photos attached of my donor.
