Hmm I didn't think about staining. That could look really nice. The wood does have a nice looking grain, so that's definitely a possibility. (Pic taken with my blackberry so not that great quality)
But Satin black would also look really nice with some silver or dark gray trim. However the trim color would detract from the tank.
go with the satin black it would look good. personaly I like stained best but paint also has a time and a place the time and place for the red is gone. the time and place for the Black has arrived. post when finished
