There's also second hand branded framesets. I had an eye on a Look recently, fully integrated, was c.1300 EUR. Something like that would be extremely hard to beat.
There's also brand new framesets that get dumped by stores to make space, often in odd sizes, to make space for the new model.
Essentially, the moment a Chinese frame isn't super cheap, relative value should be taken into account. Some markets such as the UK have incredible deals on eBay. One should know the relative strengths and weaknesses of the market they're in.
