I bought the 14" grizzly, never looked back. I searched for a long time before I got that. Sometimes you can find deals on the Delta 14" at lowes for under $400, which is a good deal. Also, I have never used one, but HD has decent deals on Rigid bandsaws now and again.
A friend of mine bought a 10" craftsman on sale for $100 last year, probably the one you are talking about ...and I think it would work, but I would not prefer to cut glass and risers with it. I think at a minimum I would get a 12" Jet..but if you cant find any good local deals, the Grizzly 14" is great buy in my opinion.
As for blades I built about 20-25 glass bows and I primarily use a 1/2" 4-6 tpi $10 delta or vermont blade. I went through about 4 or 5 of them so far building those.
