Personally I cant see it being a goer, in the past I've only bought non-Taiwan when its been uber niche (BrooklynMachineWorks) and paid a premium for it but only because of the design and not for a percieved increase in quality.
I dont think you can get much better than Taiwan built nowadays unless your talking expensive custom handbuilt one-offs.
There's no way I'd pay a premium for a UK built frame over a Taiwan equiv, and I doubt the quality would be any better from the UK.
edited to add though that something from T45 could tempt me.
My Bluepig arrived yesterday, Im curious to know (but dont expect an answer) on how Brant can make much money per unit on a £260 retailed frame thats wholesaled through Hotlines/CRC with the amount of tube manipulation on them and unique to Ragley/non catalogue cable guides/dropouts and chainstay 'fingers'. I think he claws a bit back with having Mr Wong paint them with half a potatoe though!
