I'll probably be getting that same tripod. I did look at the Giottos that KmH recommended and Manfrotto as well. The Vanguard seems to be a better value vs the Manfrotto. Based on what I've seen on line, the Giottos seem a little sturdier built but has a larger price tag. For me I want to keep the price around $200ish and the Vanguards do get nice writeups from users and the on line people reviewing them.
As for the head, I think I'm going with a Smith-Victor head vs the 250 since it has a Arca mount system. If the Vanguard ABH heads weren't so expensive (compared to their SBH heads) I 'd probably go with that.
