Check out aldelo for restaurants pro series. We have been using them for 3 years and are very happy. We purchased the hardware and the aldelo software from 1 company. It ran me $2500 for the complete software, already installed on the hardware package which included touch screen with credit card swipe, hard drive, pole display for customers to see their total plus keyboard with mouse, and automatic cash drawer. There were no other fees after my initial purchase. If you want year round tech support after the first 3 or 6 months I beleive there was a cost of about $200-$300 for the year. Honestly, anytime I called with a basic question I was able to get an answer without even having to go to tech. support. again we have been operating on it for 3 years without any issues. Very user friendly software with the capabilities for everything I could need. Bottom line I got a great system soup to nuts for $2500 with no additional costs or monthly fees.
Hope this helps,
