Yes, it's mine. I got it so I could swap tables over from my upstairs games room at home and the upstairs area of Bar62 in Ely. I've uploaded a video of me lifting JD up the stairs by myself on YouTube. Search my name Rowan Salger and you should be able to find it amongst all my other vids.
It is a little difficult to counterbalance a big super pin like JD as I only way 75kg. That's about half what it weighs. I don't want it to catapult me over! But I'm not doing any lifting, which makes a big difference. It's easy downstairs as well.
