If your cinema isn't very large or busy, and there are some computer savvy people working there, then Sensible Cinema has a pretty good and affordable solution. Since you pay only once and the software is yours, tech support (after one year) won't be as good as RTS. Years ago full support lasted one year, and then email support was free forever. I'm not sure if this is still the case? But, if you are like us, we hardly EVER need tech support. Most of our problems are busted hard drives, bad network swtiches, etc.. These are problems that are easy to solve without outside help. If you desire complicated rewards cards, gift certificate systems, gift cards, assigned seating, table service or similar things, then RTS might be better.
