Yep! If you get a good price on it. I don't think they made G20's with an MLD screen. But I could be wrong.
But in most cases, it's far too much hassle to convert a machine to MLD. You will need the MLD screen, the entire door itelf as an MLD has a different door mount and you have to redo the wiring, and a different wiring harness for power on an MLD screen.
With the parts, time and effort. It's often about the same or cheaper to just get another machine.
Plus if you convert, you lose your standard screen AVP. MLD's can't play std screen games.
I have both MLD and standard screen G23's. They both have their own good points and both have roughly the same number of games, different from the other.
Was worth getting the second MLD machine, already had my ekey and such that works on both of them.
