IF you want, You soulld be able to use a US coin mech, If you want one, I live in The bay Area, And will give you one, I have a alot of $0.25 mechs, So if you want one, I will sned you one for the price of shipping.
P.S. - I have a Super Neo 29 also, And that was the best and easyest way to do it.
Hope that helps,
