I was given a Unimat several years ago. I agree that it doesn't have the torque to do more than about an inch in diameter in mild steel (actually, I've never attempted something like steel at larger than about 1/4"), but for softer materials (soft aluminum and plastics) I've done to about 2" diameter. For somebody on a severe budget, I don't think it's that bad. You could argue that the buyer will soon want something bigger but that will always be true. I have access to a lathe that can turn 30" diameter stock.... And I've wanted things turned that wouldn't fit that lathe(*)!
But if your budget really is constrained.... Even if your designs outgrow your lathe, so what? A lathe that won't do everything you want is still a lot better than a larger lathe that won't do anything you want because you can't afford to buy it in the first place.
(*) Vera parts, actually. Gotta give my crew full credit for turning a Bridgeport mill into a very slow lathe... Worked great!
