Hello Pinside,
I've finally you entered into the wonderful world of pinball machine ownership!
I've learned a lot from this site and one thing that I see repeatedly suggested is to toss out the balls that come with a (Stern) NIB game since they are of very low quality.
The catch I see is that magnetic games such as Star Trek has a magnet therefore any replacement needs to be a carbon steel ball. Searching Pinside repeatly calls for the Pinball Life Ultra-gloss as suitable replacements.
Unfortunately these appear to out of stock and have been for quite some time. Has anyone found an equivelant replacement?
*edit
I think I found a replacement - http://www.thepinballwizard.net/index.php?p=product&id=849
After shopping by game, this option arrives for my game. I wish it explicitly said carbon steel but doesn't make mention of it. I'll contact the seller and update here.
Any advice is greatly Appreciated!
Thanks
Dan
