ebay.
all IR filters have different reflect/transmit characteristics and the nice thing about the one i got is that it comes with a chart measured off the specific filter showing its transmission characteristics. this is important when measuring IR vs visible accurately. one thing I find suspect about most reviews by hobbiests is not enough focus on the tools and techniques in the testing. for example, measuring IR through plastic safety goggles, using uncalibrated LPMs, etc.
