Ok Robert, I will open mouth and insert foot.
First, I am not familiar with any of these by experience.
My biggest concern with either is the lowest rpm
That is pretty darn fast for an unbalanced bowl IMHO. Fine once it is balanced.
Given you have your craftsman and will keep it for spindle work. I would suggest your look at the following also. Either should be within your budget.
Both EVS - Electronic Variable Speed Not necessary but very handy.
Low Speed 200 to 250
Cost: About the same $600
Bed extensions if you want them: About the same $135 (and sell your Craftsman)
Delta 46-460 or Jet 1220VS
Delta: 1 HP Reverse Yes
Jet ¾ HP Reverse No
To me the main key (safety) is much lower rpm for roughing out.
For other comparisons check here..
Good luck and hope to see some bowls soon.
