Folks,
Thanks to everyone that responded to my question. We have decided to buy a small, old, 30 horse tractor with a couple of implements that is in great shape for its age and within our price-range. We're hoping that we can pull a one-bottomed chisel or buy a larger chisel and borrow a more powerful tractor for the times we need to subsoil.
Willie: You mentioned that you used a 1-shank subsoiler for many years with a 25 horse tractor. How large of an area were you working up? Also, I imagine that it depends upon soil type and conditions, but how close did you have to make successive passes to get good loosening action down deep?
cheers,
chris

I've used a one bottom subsoiler on a 25hp 2WD for many years. Light

soil is easy, clay is much more difficult. On a 50hp, I can break the
plow in clay or on stumps.
The 10-15 hp per shank is probably for 6"-12" depth; I try to get down
about 24" with my subsoiler. For that depth, I would say 25-40hp per
shank.
I personally have no need for 4WD though I understand it is good for
frontend loaders.
Here is a photo of my Ford subsoiler on my 50hp JD3010:

Well, the top half of the plow, anyway. It is in transit position with
the point under the tractor just below the PTO. When plowing, the wide
bar is vertical and the 3 point lift points are near the ground. Not
seen is the point and about 24" of the heavy vertical bar.
In the background is my 25hp Mitsubishi R2500.
