You may just want to spend more money, and I don't know what size you need, but do know that there are several copper VC RDAs on iVapeSupply for crazy cheap. There's an X1 and a Mini Buddha in copper, also an X1 mod. Maybe just take a look via Google, because IVS has no pics up.
Just discovered, there's a 24mm Glacier in copper!

I think it was
@~Don~ who bought one of the X1 RDAs from there, so maybe he'll speak up.
OH! I almost forgot! Try code CVD50, and if that doesn't work, CNY30, for a hefty discount.
They also have other VC RDAs in stainless, even some 30mm. No squonk pins, I don't think, but for mechs they'd be great.
