For 35mm I have used some very inexpensive tripods with great sucess (sometimes stupidly called "beginner" tripods . If you want a step up to proven name brand that is relativly moderate in price there is the Bogan 3001 with a 3021 head I have one and its all I ever need for 35.

Have you considered a monopod? I hike with one all the time for the unexpected shot.
