Doosan DL400 is made i China, let it stay there.
Very few around, the used ones seems to be very cheap.
We've got loads of Doosans (of all kinds, not just wheel loaders) in the rental market here. They seem to spend more time down than up. Unless you're prepared to buy a spare machine I wouldn't contemplate one if reliability is one of your main requirements. Personally I wouldn't touch one with a barge pole. Their quality is extremely poor.
