The Wanhao is a Prusa style machine. Good value for money spent. I think it might be a better bet than either of the two initial candidates, and cheaper than both. Look for a heated bed, a bowden feed (as opposed to direct) and a large build space. Stay away from anything proprietary. Nice thing about the Wanhao is that it's a (mostly) prebuilt printer, so if anything goes wrong, you've got backup. With a kit printer you're on your own. (Not that you were looking at kit printers... just mentioning it.)

Hope that helps - Charlie1
