Nice idea to have a cocktail style arcade setup that slides away into a coffee table, and their set-ups do look very nice. But...

It would be possible to make one yourself for a lot less. Buying a standard coffee table and converting it. From Gremlin Solutions you can now buy a complete arcade control setup kit from £65 to £135, so not that expensive, and that includes everything including the i-Pac controller, full labelled wiring harness, all the joysticks and buttons... and the £135 one even comes with a coin door! Great for the price. Then it's just DIY skills with some MDF, and some time measuring, cutting, assembling, painting etc.... much cheaper than it ever used to be to do this.

And their PCs are far from up to date... I had a look and their are Shuttle SFF PCs with Dual Core Pentiums, so bottom of the current available CPUs, 500GB HDD and 2GB of ram. You could build such a system for well under £200 these days. So the cost of the PC and the controls would come to around £300, a decent coffee table suitable would probably be another £150-200, so lets say £500. The MDF and other materials wouldn't cost much more to finish it off, say £50 max, so you could built this yourself for around £500-600. A bit different to the £3000 these are asking. That is some profit margin they have going on there.
