Condors are nice, but I'd rather go for Bob jackson or Mercian if you want a full custom job. It might be a thrifty idea to buy a couple of off the peg NJS frames, bring them over with you to the UK, sell them to us (for a fairly decent profit I'd imagine), then use the cash from the sales to buy off the peg bob jackson frames, take them back to japan in the boxes you brought the NJS frames, and sell them to the Japanese for even more profit!
And of course get yourself one somewhere in between. :)
Just what I was going to say.
