Advice on a decent shop press?

Hi All,
I have a friend with an auto shop, but he doesn't have his own press.
He's helped me out a lot over the years, and I thought getting him a decent
press would be a good way to say thank you. I don't know much about them,
though.

He can fix just about anything, but has a fairly small shop, so works
mostly on family cars and trucks. Fords are his specialty. Commercial
vehicals are rare. I only have about $500 to spend, so I know I can't get
one of the monster presses. I'm hoping to find something useful that isn't
just cheapo crap for those dollars, though. Some of the things I'd like to
know...

What capacity would best suit him? Is 20 tons enough?

Hydraulic? Air? "Jack" type?

Is a benchtop press worth considering?

I've seen some less expensive presses from the likes of Ranger Products
and AFF? Anyone have experience with these?

My appologies for this being a bit off topic for this group, but I
figured other techs that use these things all the time would be the best
folks to ask.

Thanks for the help,
Max
