Welcome aboard and good luck with your 1st pin purchase .

Never heard of Big House . Had a look at the Ebay ad.. cosmetically it looks Ok from the pics but always inspect a pin in person .

In this case seller makes no mention of the condition of the boards and no pics inside the backbox either .

In my experience it can be easy to overcapitalise when restoring a pinball .

Also consider , when buying, would the theme be popular to many ? cause if you decide to sell down the track , its always easier to sell a more popular game than an unknown . My 2c anyway.
