I too prefer the look and feel of a metal frame or body. Yes arguably the polyamide is more or less as strong durable and vibration absorbent but there is something almost primitive in this guy's lust for metals. I doubt the majority of tattoists would vote polyamide to be as pretty as purple anodized polished alloy or patinad copper or aged bronze. Its just an asthetic preference but it was one of the things that I would have changed about the swashdrive gen6(that I used for everything until recently) as i wanted the amazing performance of it with a different look. Most working tools and tattoo machines are primarily metal, not just because it is durable and gets the job done but because it's beautiful and has a tangible quality feel. Polyamide looks like milk crates and shopping baskets to me. perhaps if you offered them with a nice painted finish or had them chromed. Or please make a big run of metal frames for us mountain dwarves. Larger quantity runs should also lower the cost on the cast SS and bronze versions, maybe be bringing the price down a bit from $650.
