I think I would buy the grizzly 10" drum sander G0716 and the grizzly edge sander G0512. Use the remainder for a shop air cleaner, random orbit sander (if you don't have one) and a good dust mask.
I have a jet 10-20 and have found it to be perfect for lams and bow making, but can't justify the price over the grizzly 10". I have also used a bigger drum sander once (G1079) but I really preferred the little 10-20.
