Joshua,
The current wireless coop is closed, which means that all the orders have been taken, parts ordered, and will be shipped when they all come in.
Now, it's still possible to get the PCB (printed circuit board) from RJ. You'll then need to order the parts yourself from an electronics supply firm, like Mouser electronics. Quantity one parts will be more expensive than if you bought them as part of a coop, but it shouldn't be too bad.
As for connecting your Lynx boards and your LOR boards, you have some choices. Here's only a few options - there are many more ways to do it.
1. You can run CAT-5 cable between your computer and each LE and LOR board. No wireless involved.
2. You can use wireless from your computer (via a standalone transmitter) to a LE Wireless board, and then run CAT-5 to each other controller in your yard.
3. You can use transmitter at your computer, and an LE receiver in each LE. You can run cables from an LE to the LOR controllers.
There's several more combinations.
The question also arises if you plan to use LOR software or Vixen or some other software. That may change how you connect the LOR controllers and the LE controllers, and which ones can connect to which other ones...
Hopefully, this helps out some.
PS. I see that Rick responded as well...
