i ordered one myself (the 70mw one) for 17bucks and some change i dont think you can beat it. i still have yet to receive it as it is the lunar new year and they all shut down for that but when i get it ill let you know
I also ordered one a week ago. Not received yet, but I read posts here stating that the 70 and 100 were the same yet also read the 70 was a 50 and yet another on DX that the 100 was shipped in place of the 70 in many cases. That said, I figured the 17$ for what ever they sent was a good gamble as even the circuit and heat sink are worth that. Once mine arrives, i plan to evaluate it and post my findings. I hope you post yours as well.
