The nice thing about living out in the boonies is lots of low traffic/high hills roads to ride. The bad thing is the absence of well stocked bike shops. If you want a Campy equipped bike, you just about have to go online.
I built my latest and greatest bike completely out of components obtained online. My sources were:
www.ebay.com
www.aebike.com
www.cbike.com
www.branfordbike.com
www.supergo.com
www.srp-usa.com
usual caveats apply to anything bought on ebay.
cbike has the best Campy inventory I've come across, occasionally puts wheelsets on sale. (Campy Zondas - $350) aebike and branfordbike had some obscure parts: converted Shimano cassette, removeable link for Campy 10 chain. Specialty Racing Products has a neat selection of cycle related titanium bolts and nuts, including 28mm brake caliper nuts for those of us with screwy framesets that need them.
Always check with the online retailers before you buy a bike component on ebay. Quite often, you can buy it brand new from one of the reputable sellers at the same price as you'd pay for an unknown seller on ebay. Case in point - I bought a Cateye CDW300 computer from cbike for $119. Typical price on ebay - $100-110, with no return/no warranty.
