Costco is offering a Dolica 60-inch carbon fiber tripod with ballhead for just $79.99 (Item # 661166 - regularly $99.99). Model ZX600B103. Offer good only until 11/26/12. I've never had a carbon fiber tripod before and I ordered one. Will post a review.
UPDATE: Just received the tripod last night. Heavier than I expected. Weighs just the same as the Targus TG-P60T. I disassembled the legs and was able to examine a cross-section of them. The legs appear to be solid carbon fiber (not plated).
