I wouldn't get the adapter for a regular jack unless you have a lot of room for the jack and adapter.....I have a regular ****** floor jack and love it.
Another vote for them......My old garage didn't have one and it was an ice rink most of the winter. My new garage has one and most of the water is taken out with the drain.

I was going to make my own until I priced the metal.....the metal to make the one I wanted (20 ton) was well over $150....so then I priced out a 12 ton just a little cheaper...so I bought a HF one on ebay cheap, when it bends I should have enough scrap laying around to make it...
Now this thread is funny....someone posted a compressor like that and everyone said it was junk....now the really funny part in that thread I was the only one that had a similar compressor. I like it, does everything I need.
good luck
