There's a few steel builders making full sus frames that could sort you out a custon size, but I doubt you'd get much change from £2.5k, which is around Nicolai prices :-/
Nothing else in the Marino price bracket, though perhaps Waltly have a titanium option?
Either of those two would require you to already have a very good idea of the bike's proportions
This might be of some use to you
Bikes for the very tall
