Hi guys,
A little update. The first lead which I had in the USA is unfortunately not working out.

It was not possible at all for me to select certain games, I had to go with a bulk of 28 cabs, with no knowledge of the technical condition and hardly any information on the exterior condition. Sure, there were 2 Galaga's, a Pac-man and one or two Ms. Pac-man's, but most other games involved were not that interesting for me and for you.
So I had to pass on that one.

However, I do have another lead which could be more interesting. This guy claims that he can get most of the cabs which I want. See for instance this list which I did send him, with his remarks:

Any games on the list which you would like? It will take some time for me to ‘investigate’ this lead, price-wise and attainability wise, but I’m still on it.
What I am aiming for is to get cabs over here which are technically in 100% working order, and which exterior is decent to good. Of course it mostly will depend on the prices.
It might be that I will have to change the plan with regard to financing it all, with which I mean that I might go for the route to take pre-orders for cabs with prepayments. Nobody should however be afraid that they will do a complete blind buy, there will be cab descriptions and pictures before committing to a purchase. As I said, I might do that, and I still have to work out the rules, but would you consider this as an option? Besides the financial reason another reason is that in this way people commit themselves to take a cab (I often hear people say “sure I want that”, and then later pull back for various ‘reasons’). I want some nice games also, but I don't want to get stuck with 35 of them, which is the amount in a 40ft. container.
I will keep you informed.
