I have tried two - EZ tatt and Inkinator.  Inkinator is hands down the better of the two. It is easy to use and so far the tatoos have stayed well.  I cannot recommend the EZ Tat.  I had to re-tattoo many with it and many were not legible.  It also did not go back together well after cleaning and it never really seemed to work well after that.  The support for it was good though when I called with problems with it.  I would pay double ($100 for the Inkinator - $50.00 for the EZ tatt) and be better off in the long run.
