I was only away from forums for a few days!
Thanks for the comments guys.
I can understand the thoughts on it being a sit-down, but it's actually fine to play. It's not going to be the same as a stand-up of course.
Any custom options (spinner/joysticks etc) are possible, but the intended market isn't going to know what a Happ super is, let alone differentiate it from the Sanwa. Nothing patronising intended... it's just a sit-down-and-play. Needless to say though, there is a reason behind all aspects of the design as it wasn't thrown together over a few weekends.
Thanks for your comment on the price uprightbass. You got it. It's a common justification I have to make, but I understand.
The manager of OneDeko actually sold the system in the shop to a rather keen customer and I am replacing it this weekend as he also wanted the new shiny piano black version, which looks fantastic... and so it should with a £400 paint job! So if anyone is looking at heading down there, drop me a message first to make sure it's back in.
I'm getting some more photos done very soon and I'm aware I need some action shots. They are on the large list of things to do!
