I'm interested in getting a tripod for my Nikon D50, but unfortunately I have no clue what I should get. The D50 has a 18-200mm Tamron lense, which I think puts the total weight at just over 2 pounds. I don't plan on buying any heavier lenses in the future, if that will make a difference. I'm looking for something for pretty common use, it doesn't have to be extremely stable, just something for a ameture photographer (in the 40 dollar range). If someone could point me in the right direction that'd be great, I don't have anything against buying off eBay but I'd prefer it to be new. Thanks for your help.
