Can you make Money putting machines on Location?

Right. As Lloyd said, you'll need to learn what games your customers like. I operate pins in a nerd/gaming themed bar and co-working space here, and the spread between the popular themes and the less popular ones is pretty huge. GoT Premium was paid off after around 12 months (after split). Hobbit is on track to reach that milestone after about 18-20 months. World Poker Tour, on the other hand, is not the right kind of gaming for this crowd, so that one seems to land more in the neighborhood of 50-60 months...

Considering our clientele's preferences, we have skipped e.g. Aerosmith even though I personally would have loved to play it. On order currently are Alien, Tron, Dialed In and Star Wars (LE, to get the full package as quickly as possible, and because we're geeks after all). Dialed In is a bit of a wildcard, but we have enough hard-core regular players these days that I think that game will be popular. For the same reason we're probably going to go for a Total Nuclear Annihilation.

Haha, yeah "On order" is not the right wording in that case, I guess. We're buying a used Tron from a fellow collector, and are just waiting to get shipping sorted out, that's all.

In our case, yes; but only because we have established a deep trust with them. They handle the odd ball trap and on a couple of occasions have changed a broken slingshot rubber. If we didn't trust them 100%, I would much rather take those extra trips down to fix those issues myself, rather than risk abuse or being ripped off.
