Not one to simply
post a link to this in the Price Watch section, I actually bought the Nest NT-6294 carbon fiber tripod at the $147 sale price! It has thick 29mm top tubes and 4 sections with their innovative "limited rotation" leg locks (1/4 turn until it stops either way to lock/ unlock). The detachable monopod leg and automatic, 180° leg angles are nice extras.
I was reviewing its smaller sibling (the 6265, five sections, smaller 26mm top tube), and liked the blue aluminum leg locks and build quality enough to finally replace my 11-year old Feisol 3401 (which has plastic leg locks that rotate whenever the upper section is loosened). Not really an "upgrade" in terms of size or weight, but I think I paid $250 in 2003 for the Feisol, and this was just the deal to push me over the edge.
Expect to see a Feisol 3401 carbon tripod for "a very good price" in the next few days...
