Tri,

We are already in contact with the Cheap Beep Project transmitters.
For receivers at low cost I recommend using a scanner receiver. There are only five of the hundreds of models that are suitable. I will send you the list. For falconers outside of North America I consider the Yupiteru MVT-7100 purchased on Ebay.co.uk to be one of the best options.
