You can put a Peregrine together for less than you might think. I got the frame, forks and a selection of bits (levers, no-name bar tape, gatorskins, Open Pros, SLX hubs, spokes, chainring, chain, tubes, ) to the value of £940 from A Shoppe. Bought a couple of things cheap from . on-one - BB7 calipers, bars, headset) and a few bits from the parts bin - ST cranks, BB, saddle, seatpost.
Started SS for fun and savings. Bit later I bought a cassette, Dura Ace bar end shifters and rescued an old mech for a ride on the SDW. Oh, some knobblies too.
600 after tax (ish) + £150 in bits from On-One, + parts bin stuff for the 1st SS road build.
I can send you the spreadsheet if you're interested?
