I'm looking for a lower cost source for a 38kHz infrared receiver module that is identical to this one http://www.radioshack.com/product/i...roductId=2049727&support=support&tab=features sold at Radio Shack. Specs are 2.4-5.5V and 940nm pass band. Any idea who the manufacturer is and where to get it? I need a bunch of them and $3.69 each is too much.
