Manny used to do very good work, as lots of people here can attest, but he's no longer got access to the necessary tools.
The pictures posted of that cab - regardless of incorrect dimensions - look pretty rough and poorly finished if the price was £1k .....
Cosmokramer on Pinside was working on a flatpack WPC cabinet project. They look very good. However he's put that on the backburner whilst he tries to work out shipping solutions within the US. Bulk orders going via pallet internationally ought to be easy, if he does start offering them again in future. They looked really good, assuming you have the skills and tools to put them together.
I haven't heard particularly good things about any of the kits or fully built cabs available in Europe. You could ask Pinball Dreams to sell you one, and I'd expect it to be top notch, but you'd probably be paying top end.
