Metal lathes are one of those things that range in price AND quality from fairly low to very high. I don't have experience with any of the models currently sold in that price range. I know you could get a Chinese made lathe in that size for less than half of your budget and then get about half of that back in resale if it did not have the accuracy needed. Putting a metal lathe on a mobile cart may not be a good thing for accuracy if that is what the cart is for.
