I buy homegrown shrooms from a friend for 25 and they are the SHIT!!! 30/35 is ther regular price for an 1/8. Might be a little more in your area. An 1/8 should be fine, jsut take half an 1/8 when you start, and if you are still feeling ok with the trip after an hour or 2, take another half 1/8. Just prepare yourself mentally, and you'll have a great trip. There is nothing to worry about.
