Neotat vivace in my opinion is the best rotary out there.. Used Pretty much everything and now have 2 neotat vivace a 2.5 for linework and a 3.5 for black and grey for colour you can line with the 3.5 but i prefer a shorter stroke liner... Get the 3.5 if your only getting one!! Its amazing.. The only other machine i need to try is a swashdrive whip... They look great but never tried one... Neotat beats everything else.. In my opinion
