The radial drill press mentioned is a great buy because it is the only one out there. Grizzly offers them for less than 200 dollars. Now they are really cheapo presses. But it has a really great throat on it. I think that it has a 36" swing on it. I use it to make telescopes. I had to put a more powerful motor on mine and I never use the round table as is. I put a table on top of it and shim it to be perpendicular to the bit. I use a a low cost Jet mill for my other drill press.
Another benefit to this press is that you can drill at an angle as well. I don't know how useful that would be for guitar bodies, but it would be pretty terrific for making chairs. If you don't need a big throat or drill at an angle, I'd shoot for a floor mount Jet. Good value.
The little bench band saws are slightly more beefy than a scroll saw. I imagine that you could cut the outer edges of a slab blank with one. But I wouldn't count on it for anything else. I had one for a few years and never really found a use for it so I gave it away. If you are dreaming of a band saw, get a 14" with riser blocks. Shoot for a 1.5 HP model if you can get one. I have a preference for Delta and Jet units. Grizzly is getting there with their tools, but you'll find fewer problems with the D & J. I've got my Delta tuned up right and it does resawing really well. I've made other things with my veneers. I can't wait to make a guitar.
