I just recieved a Marin from my grandfather, it is fairly new, probably 2 model years ago, and i was wondering how much it is worth, he doesnt remeber how much he paid for it, and it is a hybrid, so i thought u guys might know. MArin San Anselmo, 19" i am thinking of asking 600 or more for it, but if u guys think that is outrageous please tell me.
