From a business or even a loose change earner for people like us wanted to get a bit of a return on games to build a collection, I think it might be a hard way to make cash. Have a few out there like 5-10 and you could find yourself having no evenings for anything else but repairs. If you only service 9-5 there maybe a chance people might continue to play while waiting and causing further damage. Leasing sounds great but in real terms I think a waste of time. Tv's, cars, washing machines don't tend to beak down too often and so the risk is minimal.
The weekend deal is probably better as guys will probably crack it for awhile if it breaks down and then just settle down and drink for the night???????
