So I've got 3 fever pachinkos (Indiana Jones, Robocop, Star Wars) and 3 pachislots (Samurai Spirits Swordsmen Match, Lord of the Rings, and Fever Queen I).

I'm at the point where I'm interested in trying out data counters, but I'm not sure what models to look at. I want something that will be compatible with what I’ve got, that is feature rich enough to be interesting, and that is accessible to an English speaker. I'd also like to get a model that can be easily found in the event I like it and want more of them. Any suggestions would be appreciated.
