Can anyone recommend a good but reasonably inexpensive tripod? I am looking to spend less than $200, but want a good tripod that is sturdy and somewhat lightweight? What is the best material in this price range? It needs to be able to hold up a Nikon digital SLR, a Nikon FG, and a Mamiya m645 1000s. All of those cameras won't have huge zoom lenses, so I'd say the heaviest product is the Mamiya, which is probably around 4-5 pounds. Thanks!
