galvanic / therm unit for <$600

Hi All,
I am new to this site and thought it would be great place to find a used or new epilator capable of blend that is better (stronger) than the OneTouch. I am not looking for anything fancy or digital - just something with more power to use between my professional sessions. My skin can handle a lot of current right now. That might change with more time on estradiol

Thanks for your help.
