I have used hand knit patterns on both my standard and chunky metal bed knitting machines. Providing that the swatch that is knitted on the knitting machine matches the swatch in the pattern you should have no problems. Having said this, I wouldn't buy a machine with the idea of using hand knit patterns. Buy a machine that will do all that you want it to do, a machine is far more expensive than a paper pattern. There are so many knitting machine patterns available and other ways of designing a garment that I would suggest that you forget the original idea of why you thought of having a machine. Research machines to see which make/model will do what you want.
