the mech I have currently installed is adjustable -- it was using tokens, but the coin door was slotted for quarters. I'll track down my digital camera to get a picture of it. I can at least give you the brand though... it's a ... hmm. =) It was manufactured in oldham england, so sayeth the metal engravings (stern coin door, that mean anything?). It has a sticker on it that says "coin controls <symbol> elk grove, IL, USA". Anyhow.
I'll be using tokens that are slightly larger than quarters.
