Forgive me, but do you have a guess on when these might be available, and even a rough idea of the price?

I'm asking because - it's been so cold here lately I haven't even kept the empeg in the car, just listening to NPR on the way to work and back instead. It would be a good time for me to send the empeg to you for the LED's to be added. But I don't want to do it and have to wait half a year for the buttons.

Hope it doesn't sound like I'm whining! Just trying to get an idea of how and when I want to get it all done.
