Just my 2 cents; My Bride of Pin-Bot coin door is in Deutschmarks, Factory restore makes the game in German, and the power says "Vorsicht 220 volt" on it. If that isn't proof that the game was re-imported I don't know what is. There is none of this alleged "salt water erosion" so many people talk about.
If you find a title you like, and it is re-imported I wouldn't steer away from it (As long as its back to the correct power you need). Hell. With the stigmata of imports, you might even get it cheaper than its non world traveled counterpart.

Whoops yeah I was slightly off with the stigma/stigmata part. Either way, my BoP was about $300 less than all others in a 15 hour radius at the time because of the whole re-import thing. I am sure some people have had horror stories with poor maintenance/repairs on re-imports, but the only repairs I have had to do on mine was swap out a solenoid, the shooter lane switch and some bulbs in over 5 years and 1k+ games.

Good luck with your decision and lets hope Indy will soon have a new home shortly!
