Harlot -
I'm about to get another track frame built up. This will probably be the all-track ride, started because I managed to get Campy Record Pista parts for a steal. I'm going british this time, sort of an homage to my earlier years and a Bob Jackson is being inquired about. Not fully custom, this one is an "off the peg" Vigorelli Pista 631 Reynolds frame which comes in the colour and lug pinstriping of your choice. Full custom comes at about $1000 shipped and a Mercian costs about the same. I hear the wait times are shorter than their American brethren. The off the peg though is a 10 week turnaround. Better than a year but maybe not so good if you want it for the here and now track season (which is almost done soon).
Edit: the off the peg costs about US$640 shipped.
