You can get them from Laipac in Canada. They have a $US25 minimum order but
they also have the RF receivers so they may be your best source. Here's a
direct link to Laipac...

Get the RLP receivers (tunable) and TLP-A transmitter.

You can get the 4-pin or and older 6-pin model from several sources. All the
sources I know of for the Wenshing designs are listed on this web page.

You can find other small transmitters at Abacom (Canada) but I think they
only have one model that is 315MHz and it's a bit pricey.
