Now where can I get a small black argon bottle......

You can get a brushed no-coat (ie matt silver) 6cf one from
Dive Rite Express. That would fit your colour scheme I beleive...
You could also get milspec non-magnetic all-black regs from Apeks if you really want the stealth look...
PS - I'm not really serious about that last suggestion - put the credit card away now...
