The other option (which is what i did) is to look in the Yellow Pages and find a local anodizer...
You'll obviously have to strip your marker yourself and know which parts you can ano and be able to put it back together again!!!
I got my 2 cockers ano'd and chromed for £55 - (fifty five).
2x Body, 2x back block, bottom line, 3 barrels, reg, 2x vertical asa, 2x anti-tamper, stock, bolts, powerfeed etc, etc
You need to trust the person doing the ano as you won't have any comeback if they f@ck it up so try and get a personal recommendation.
