Spoke to a local salesman a few years ago when we were considering moving house and looking at woodburner options. He had been approached by a local "celebrity" who'd had two or three stoves fail dramatically, all were the cheaper type. Generally he said the cheaper stoves are poorer quality metal, hence warping and cracking. Spend a bit more if you can, but if not don't expect them to last forever, but that's not to say you wont get lucky! +1 on clearview.
