I got my Litespeed from this store:

Drove down from Orange County to San Diego to pick it up. You might want to call them and get their 2 cents. I've never had any issues with my frame so I can't comment on LS warranty problems.
FWIW, I got mine in Sep 02. Sep seems to be when LS and Merlins typically get price-dropped a bunch, as in over 30%. I never could find a comparable drop on Trek (5500) so I opted for a Litespeed. Originally, I wanted the Merlin Agilis, but the Ghisallo went on sale (w/ fork) so ridiculously low, I got it instead (I had to drop from a D/A to an Ultegra build in order to get it past the "Committee").
Sep is right around the corner - you might want to see what shakes loose in a month.
Best.
