Bandsaws are not too hard to rebuild... new bearings and blocks usually do the job. IMHO you're better off to get a used 14" full size than the little ones. Blade life can be a real factor in a small saw, especially with a 3 wheel. You want the blade going over the largest diameter wheel you can.
I run two Grizzly Ultimates and love them. One i bought new and one I bought as worn out salvage from a door factory and rebuilt to new. I keep one set up for shape cutting like risers and the other permanently set for resawing lam blanks.
One other comment, and everyone doesn't agree with me on this, but after investing enough in blades to have bought the blade factory, I learned to never, ever cut glass with a bandsaw. I just don't do it. I use a miter box and hacksaw for any cross cutting of glass lams and I use a belt sander for all limb shaping. I use a combination of the belt sander, spindle sander and rasps for shaping risers. I cut my shelf in with rasps. Cutting even one inch in glass will ruin a bandsaw blade. You can make them last longer if you get into bimetal or carbon blades, but you can end up with $125 blades! I get about six bows out of a $15 sanding belt.
