Well I admit it blagged my head for a while but there are plenty of small businesses out there that cater specifically to our hobby.
I used Paul at Sabotag3d and find him great. Buy the file, email to printer, get a quote for how many you want and off you go. As I was changing the scale from 28mm to 40mm we needed to print some samples to get the scale to match Perry's and check the quality was good but end result is brill.
Cost wise its been pretty good, cheaper than metal if you use the file more than once as I have with the Hessians(file with 6 marching printed 6 times to give me 36 marching figures, cost of file is paid once and split over the 36) figures printed , and if I had spotted them sooner I would have bought the STL file for these Piano Miniature cows and had them printed too.
