i've ordered from ben's in the past with good results, but...
though i haven't even received my order yet, i already like the service from Track King on ebay.
their prices are about average or a few bucks cheaper than other ebay sellers (ben's bike, for instance), but they take paypal (which is about the only way i'll buy or sell, these days - ben's does not) and offer free shipping on most smaller parts, which seals the deal.
i think i ended up paying $5 to ship my whole order - bars, pedals, clips, straps, and grips. not a huge deal, but from other sellers, that stuff would have been $5 each to ship (or more like $10 for the bars), so it adds up.
terrie was also very receptive to my inquiries, answered promptly and even ordered a handlebar i wanted which the store had not previously stocked.
that's enough to win my business.
