Looks nice Nob, same road I´m going but thinking of this:

ISP frame that should save me some weight saving in theory. Been looking at Srams TT900 shifters, I think they can be modified as downtube shifters.
You need to tread carefully buying expensive stuff from China. There was a guy on another forum who wanted to save some money, and found a great deal on a TI frameset, guaranteed for life, from a well-known Chinese TI frame builder. The bike arrived at his house 8 weeks after ordering, which he expected, started to put the bike together and the headset would not fit, he mic'd it and everything seemed to be ok, checked the treads and they were all good, so he took the bike to the bike shop, the bike shop discovered the headtube was slightly ovalized instead of round. He contacted the factory they told him to send it back and as soon as they get they would send him another frame, so he did, and he waited, but no word. contacted the factory, and they told him that he damaged the headtube and they were not going to replace it under warranty, they said they would send back the old frame, he never got it back.
Americans are completely powerless to do anything about that sort of thing, China does not obey nor conform to western laws and rules. So he was screwed out of his money and bike.
If you have the money to gamble with and don't mind the risk then fine, because some people haven't had any trouble with Chinese direct-made stuff, but you could, and that's just one example I've heard of, I've heard of a lot of others.
