looking to get a high-end mech to outshine my ugly modded sigelei #19. atmizoo roller looked like a cheaper and promising buy, but it costs 185 shipped for anything better than plain brass contacts. a black sentinel might be cool, but how do I know I'm getting a real grand vapod mod from the vendor? I'd like it to look good with a richman rba or the AL-1 I pre-ordered. I also think the atom looks really nice. any experience and opinions very much welcomed. my criteria are (in this order): performance and durability, looks, dollar value.
