FYI - You can anodize in your garage pretty easily if you want to. Not sure what quality you will get the first few times, but I've read up on it and it only requires a battery charger, some battery acid, a couple of pieces of metal, and some RIT dye.
The results I've seen online look pretty good. I've used a similar process in reverse to remove rust from my auto restoration projects.
Do a google search if you like doing this kind of thing for fun.
