Hi, i will try to help a little Personally this depends on your intentions as to what machine would be more suitable, are you mobile or salon based ? apprx how many tans would you be doing daily (max) upto 10, upto 20, upto 30, 30 +
i would recommend a unit with 0.6mm needle in the gun, stainless or teflon
make sure your hose is long enough for movement, If using for more than home use, I would advise a compressor unit with a filter this protects the motor from airbonne particles in the room being sucked in to the unit.,
The tanning essentials T200 unit is a great starter unit, The Ts-20 and the classic (good starter units for smaller businesses )
next step glam by tanning essentials, (good small business option)
fully salon pro units :- pro by tanning essentials, earlex ts50, maxi by tanning essentials (more salon use units) TS-50 great for mobile also
