I have found a Jet JWBS bandsaw 1 1/2 hp in good condition for $450.00. I have a few questions concerning the saw. I am considering buying and upgrading the motor to at least a 2 hp. Does this saw have cast iron wheels? To owners, would you buy again? How does the saw rate in comparision to other 18 inch bandsaws? If I could get a new motor for around $300.00 I feel it may be worth it. Thoughts???
