Gitzo and manfrotto are Creme de la Creme and expensive to boot. But there are many good less expensive ones which work. Which type of digital camera is it - point and shoot or something heavier?
Folding tripods with three leg sections are more sturdy - when you have a heavy camera. Otherwise a good one should allow you to change height from about 20cm above ground to eye height (for binocculars). Search amazon forow cost ones and check the reviews. I bought my father one for about 80 Gbp a couple of years ago. It had a small water bubble spirit level and lockable ball head. It's all be needed for his canon rebel and 450D devices. Sorry can't remember the brand
