SJS do a thorn crank triple - that comes in so many lengths - that's what's on my off road fixed... stick a bmx ring on there and you're away.
Although over budget my set up is:
A freshtripe single speed saracen
NS Bikes single speed disc hub (rear) to use a velo solo bolt on cog - this gives a much more convenient 46mm chainline and has much more scope for chainline adjustment
Thorn 160mm cranks (gearing's a bit low as the max chainring I can fit is 40 and the smallest bolt on cog is 16 - 15 clips the chain) so this helps
Hope front hub
bits and bobs etc.
The thing is if you buy a good wheelset as above you can stick it on an old style mountain bike for now then build up the frame etc. whilst you're riding that - then swap them over.
