Hey bud, I would tell you to avoid that machine like the plague.
I'm here in Wichita as well and that machine is at the A-OK Pawn Shop on West Street between Maple and Central. It's been there for quite awhile. In fact it was bought a few months back, and then re-sold back to A-OK within a matter of weeks.
Also as you might notice, this isn't a dedicated Sunset Riders cab. It's a conversion from a 'Main Event' cab:
This is why the joystick and button placement is swapped for player 1&2 and 3&4 (joystick on left, buttons on right vice-versa). But even more odd, it's only the two player version as they put button for player 1 and 4, but no joystick. The monitor is also different from the original and is quite tiny (especially for a four player game). Bottom line: It's a frankencab.
They now have it on sale for $300, but even at that I would say pass. If you're looking for a Sunset Riders, try and find a Konami 4 player machine. Funny thing is my first Sunset Riders cab was the same thing, a Mian Event conversion). I sold it a few months later when I found a dedicated Sunset Riders machine and I have to say there is a huge difference.
Hope this helps and good luck!
