Seconded. I own about eighteen 25 cent bulk vending machines I've had for about 5 months. The profit seems HUGE for 5 hour shot machines. I have seen some from Vend Rite that look promising. They are very compact and can be wall mounted. I have asked my local Sheriff's office if they would like one, they said they would get back to me. I'm also wondering if someone could direct me to a thread about accepting credit cards on machines?
