The guy I bought my bendpak 4 post lift from had a mid rise bendpak, it was pretty nice, he cut the floor and dropped it in like 4 inches so his Porsche gt2 would clear driving over it.
Bendpak is the highest cost and the highest quality.
With that said, the velocity channel runs a commercial all the time one that is fairly cheap, quickjack is what it's called

I think it's more of a low rise, but some models are less than a grand.
My original plan was a mid rise, but like anything else I do it quickly escalated.
I think the issue for me with a mid rise was that it's really not good for anything other than suspension and wheel work, things that realistically you can do on the ground if need be. I don't think you can pull a trans with the inner works in the way, besides not sure how comfortable i'd feel under one of the completely.
Look into a small 4 post that you can use a slide jack on. Some are short enough that you can actually roll them out of your garage (I think). Downside is that if you use it for storage of a car, it likely won't go high enough to walk under. My bendpak goes to about 6.5-7ft with my car on it, so I never have to go around it in the garage.
