I also have the Harbor Freight lift table. Works really well. The front tire vise is sucky, so I replaced it. Got it on sale last year for $249. I was going to buy a Handly Lift, but it ended up being close to $1500 delivered.
Since I have gone alot of years without one, and not knowing if I would actually like a table lift, I went ahead and bought the cheap unit. Figured the metal decking was worth the cost of the whole lift and I could use the material for other projects if the lift turned out to be total crap.
So far, I like it. I don't use it for everything, but it sure beats sitting or laying on the floor. Oil changes are nice. It's pretty sturdy.
Quality wise, it's not bad.
