Responded to your other topic on food budget. Recommend on gear, you as suggested previously seek out good deals (look on ebay). Also this may work for you, rent your gear—some outfitter have some used gear you can rent. Additionally check with the members of hiking and backpacking clubs in your area, you may be able to get the loan of some gear for nothing or for very little cost. Since you are a novice, I suggest you do not put a lot of money into something you know very little about and have very little experience in. I also suggest that before you do this 35 day hike, you do some overnight hikes and get yourself in trail shape and learn a lot of the basics from these overnight hikes. A lot of people spend a lot of money on equipment such as packs, stoves, sleeping bags, etc and discard it along the trail within the first few miles of their hike when they realize how tough hiking is. A lot of good high quality gear is thrown away yearly by would be AT hikers shortly after leaving Springer Mountain, the start of the AT in Georgia. Bottom line, before you try to do it, get in the best trail shape you can. Hope all of this helps.
