Their prices have risen quite a bit since I first started using them but the quality was always top notch in comparison with other shops. I have a few local shops that I use when “just OK” is a priority.
E Proto (great appearance models, I use them all the time)
All Jack (low to medium volume manufacturing)
Dutch Group (good appearance models through to low vol manufacturing)
Hemtom (good appearance models)
Image (great appearance models)
Forecast 3D (3d print, additive metals, 5axis CNC, and urethane casting facility with some post finishing capabilities, but only a few miles from me)
Shoot me an email Jon if you want me to send you email contacts to any of these.
We used Image a while ago for some nice appearance model work as well. Alljack used to be a model vendor, but they lost a lot of staff then re-emerged so we never used them after that.
