For the last 5-6 years I have been asked so many questions about rotary tattoo machines. I'll be producing a video download next week to give you my review of ALL the rotary machines I have used, their features, what they are best used for, pros and cons...the works. I'll cover N2, Neuma Hybrid, Swashdrive, Swissmade, Stealth, Stygma, Hawk, Neo-Tat, Dragon Fly, Bishop, Inkjecta and all of the cheapo knock-offs on eBay. I'll make it available on www.tattoosbykeith.com for about $20.
Think of it as investment that could save you hundreds on your final decision.
Hope this helps!
