Just adding to the praises of Hemispheres - My story is that I bought my very first two pinball machines from Kurt back in 1997 at his original location. One machine was brand new & the other a clean 'used' machine. (don't think the term HUO was invented yet ) I remember not knowing anything about pinball & was hesitant to buy due to this. He showed me around the store as I tried numerous games while he explained the features, what to shoot for, etc. He didn't place any pressure on me to buy, and actually warned me that these require a bit of upkeep. He assured me that if I ran into issues or had any questions, he'd be happy to assist. I ultimately selected two machines, he loaded up my truck and went over with me how to install the legs and setup the games when I got home. I only had to call him once after that with a basic issue on one of the machines and he gladly walked me through the fix just as he promised. I left pinball for a decade or so following a divorce, but when I got back into it, (& joined Pinside) I reached back out to Kurt and bought a restored machine from him. His work was so good that when I put the 20+ year old machine in my new line up, most of my non-pinball friends couldn't tell that it wasn't brand new, like my other machines.
Long story short - Kurt is honest, has integrity and can be counted on long after the sale. And from what I've seen in other instances, (pinball & otherwise) that type of business person appears to be a dying breed...
