I would definitely rather have ads than have a subscription-based pricing model. I feel a lot of the people that post unique and somewhat rare items for sale would not be willing to pay as they post so infrequently. I would not mind paying myself since I post more than others. Maybe we should restrict the number of posts you can have running and make it where you have to pay to post say more than 3 at one time. That would supply additional revenue and not take away from the classified section as much. Just my two cents.
