Can u suggest power supply?

Can anybody suggest a good power supply? I've been thinking of buying a digital one from Superiortattoo, but I've had some negative comments on it. Any ideas? Someone suggested Instek digital power supply (www.unimaxsupply.com)... what do you think? thanks.

Hey there I would highly recomend the power supply made by PULSE www.pulsetattoo.com I've used it for several years now, and have been more than happy with it. J. Capobianco

Wow. If Joe said it, it has to be good. ;o) Thanks for the awesome tattoo joe. ;-)

why not ask your teacher mentor liason ya know the person thats PROPERLY TEACHING YOU TO TATTOO. pulse looks good eikon is one of the best unimax ok there out there but you should be asking your teacher this could be considered tech question or even worse and dont take offense but this could also be taken as a question from a scratcher pleas dont think im labeling you as such
