I've got a cheap Trangia copy (not sure if it's the same) and it's pretty good, it's not as durable as the real deal and it's far from non-stick, but at that price it's worth having around!
I got one from Lidl on Monday and whilst it's a good value stove I had to get it changed twice. Once for bashed burner and then for missing bottom frame/burner holder (that's right - the main bit).
Good thing is that they exchange without question, but check next one before you leave the shop.

PS beware ebay. People are selling the £7.99 Lidl model for £18 and MORE (plus postage). Nearly Trangia prices (no R ).
