The White Industries wheelset is far from yeoman dude, assuming that the bearings and cassette freehub are not toast. The hub flanges on these seem to hold up better than Ringlé and early hope, thank goodness.
The crankset is also a USA made WI set and not the Sugino licenced ones, so worth a little bit more..
Agreed on mech and brakeset. Control Tech stem and bars worth maybe £20-30 if they clean up well. Same for the seatpost which looks to be a CT as well. Likewise the Judys may fetch around 50 bucks if they aren't shot internally.
X-Ray shifters could be worth a little, but these seem to be a bit too battered to be worth much. I spy cracks in the clear housing which was super common on these.
The frame isn't really worth shit though. No massive demand for retro sweet spot sus frames these days, especially one from an unfashionable brand, with a ratty top tube and suspect rear shock. The hardtail Homegrown of the same era is a nice riding frame (built by Yeti) but even those are cheap these days.
A few hundred as a complete bike is bang on the money :)
