The last time I had some wheels built, the price was a lot lower, but that was some years back. I just checked with another builder and he quote almost the exact same price. I guess this is what wheel building costs nowadays.
I've posted this a few times before but if you delace, measure the hubs and rims, order some spokes and relace it's only a couple of hours work and you'll only have to pay £5-£20 to have them tensioned and trued by a shop. Worthwhile skill and you'll save £100-200 based on those prices above
Is this just accepted a kosher price for wheel building these days?
Last time I worked in a bike shop I think the labour on a wheelbuild was like, £40!
