There are a lot of cheap, badly-made rollers out there. This site is a well of info. Unfortunately, like acne.org, it's a lot to consume, but suffice it to say Dr. Roller and Owndoc.com have a lot about scams and rolling to help anyone thinking about it. http://owndoc.com/de...aroller-review/

ETA: CAVEAT: Pumpkin says she's not a good source.

(Sigh.) This is what I know--Dr. Roller is well reviewed and uses the quality of needles one needs for derma rollers.

I would really appreciate it if someone could direct me to a source that sells safe dermastamps for under $50. http://www.acne.org/messageboard/index.php/topic/293715-attention-to-those-that-have-used-or-are-using-a-dermaroller-dermastamp/page__st__60
