That's surely a solid band saw. Let's assume that's in a good working condition, you'll never go wrong with $125. I couldn't tell by the picture if it's both for wood and metal cutting. Wish you luck.
It's a solid looking band saw. I like Grob saws. Can you tell how much does it weigh? How'd you get it on the truck? I'm sure you'll be pleased with it.
That looks like a great deal! Here's an info http://www.dakecorp.com/products-detail.asp?page=Work-A-Matic%20SXC I mostly use bimetal blades I got from sawblade dot com .
Is it only for wood cutting? That's a fair enough price. Missing parts are easy to find. I think you'll be pleased with it. Just proper tuning up and maybe some upgrades you think you need for your plans.
