In the same spirit that I recommended Overstock.com for suits - check out
http://www.thetiebar.com/ for ties. They're inexpensive, nice looking ties that don't last FOREVER but so the fuck what? Order some cool silk ties for $15 and throw 'em away when some of the threads start to fray. I got about 20 when I started at my old firm and, given that they each get worn about once a month - most are still in solid shape.
