For a hobbyist (or production worker) PM 3520B is hard to beat.
Choosing between a 3520B and one with less capacity lathe that cost more is a no brainer IF you are on a budget IMHO. But the ultimate factor is for you to test drive both and see if the quality is that much different between the 2 to consider the trade off (cost and swing). I know either way you will get a winner.
Good luck with your choice!!!
