Well whats happened to the anno service as I dont have an account( wont let me sign up :S ) but im interested in getting a marker done( well toying with the ideA).
for up to 5 parts i think is about £30 quid and up to 15 parts £90 - £100 ish every part after 15 you pay a little more, i'm not 100% sure on the prices you best bet is to give em e-mail http://www.slothball.com/ Anodising@slothball.com
