Wow! Thanks for all the replies! I'm impressed and lucky to find such a knowledgeable group!
Well at present I have a 25 year old Craftsman that I bought new. It used to run fairly decent but with a little vibration I haven't used it in several years and was disappointed when I turned it on and ran it through the speeds and near the top end it was vibrating so bad I turned it off for inspection. The tension had vibrated loose It has a small knob on top to adjust tension I retightened it but didn't have enough strength in my fingers to get it taunt. I could push the blade with my fingers and it would go back and forth about half an inch. It is a Craftsman built in the day when Craftsman stood for quality. I suspect that it is a Delta, rebranded to Craftsman. It's a large saw and it came with a stand. I think I paid $300US for it back then. I tried to saw a little 1/8 whitewood with it ant slow medium and fast speeds but it would barely cut. I'm going to buy some blades tomorrow at Lowes or HD and see if thats the problem although it vibrates bad when I'm not cutting anything If I could get it working with minimal vibration I could save myself a $1000
I'd show pictures but I can't get farther back the about 18 inches from the saw! [EDIT] found a manual online with a picture of the saw on front!

Thinking about it, that SS was a pain to change blades on! I wish I could try some of these cheaper saws at Lowes first, I might fine one with acceptable vibration but they are not set up to do that
