Guys
need some suggestions for my first to be tripod.

The camera is Canon Rebel xti, a kit lens and a 75-300 lens.
My use and work is not so delicate, mostly outdoor. Nature photography.
I need a sturdy but inexpensive 70 inch tripod. I will need to carry it everywhere.
( Asking too much, am I not )
Any suggestions?

Thanks

Amol
