I'll second the comments on the radial drill press. Quite a while ago, I had one and ended up replacing it with a 'regular' drill press. On the radial press, quill travel was limited, also there was a lot of chatter when boring holes. So unless you put a crow bar in your wallet and put out a bunch of money for a sturdy radial drill press, I'd go with a a regular one. I had the same experience as Tom: I hardly used it to the full swing, but used it 99% of the time as a regular drill.
As for brands: My latest purchase of Delta and Craftsman power tools were disappointing; I will not buy anything elase from either. I do believe that you will be better served with a Grizzly, General or -best of all- a Rong Fu.

Have fun shopping!
