I have an Induro aluminum 3-section travel tripod that I can recommend - it is sufficient for a 35mm/DSLR with a normal lens or a compact zoom, or a medium format rangefinder/TLR (I used mine with my Rolleiflex in France last year). It was about $100 new ( Induro_472_013_Alloy_8M_AT013_Tripod ). Another option to look into is the Travel Angel ( Benro_A2690TBH1_A_2690_Travel_Angel_Aluminum ). They're more expensive than my Induro, but they fold up even smaller and are just as sturdy. The Travel Angel kit includes a ball head for the price, so it really isn't THAT much more than the Induro.
Find the lightest strong tripod that you can find. Look for aluminum or carbon fiber tripods. Anything else is guaranteed to gain weight with every step as soon as you are more that 100 yards or 100 meters from the car.
FWIW, my Toyo 45A-II on a cheap Dolica carbon fiber tripod. It's much easier to pack into the woods than a Manfrotto 3021/3047 combo.
