I'm looking hard at this OBS to purchase. I just can't help it, I am attracted to, THE ALIEN...Anybody have the black version? If so, I can't find any info on what the finish is. Paint? Ceracoat? Other? How is the black finish holding up for you? The pics I have found, it shows the threaded portion of the 510 to be black finish also, any conductivity issues? Not a deal breaker, I also like the SS version, black would be first choice. Also, Any chance they will offer a replacement tank section in the event of a break? I also like the rba section, beefy screws, looks like a must have for this system.
