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….500-600.
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.

Good luck and hope to see some bowls soon.
