My 2 cents. The Cheyenne thunder and spirt tattoo way nicer than the edge. I really want to like the edge.... but it just doesn't tattoo as nice. It's not as smooth as the thunder it has a vibration that isn't that big of a deal but can be annoying if you're used to a Cheyenne. It feels underpowered somehow as well... the thunder lines like a Lazer and the edge I find myself constantly tinkering trying to make it line as nice as the thunder. The give on my edge is defective or something because it basically doesn't work. I still have my original hawk cable and it's never shorted out with years of use.... I go through an rca cord every month.. Cheyenne equipment has something special I can't find in other machines. I've tried a lot and I always end up back with the thunder for everything.. it lines shades packs with ease.
