WTB: MS13A or MS14a Motion Sensors

It's hard to believe but my automation box is out of motion sensors and I need a couple.
I'm looking for cheap or even free if you feel like helping me out. (I pay postage)
post here or email dakers1@twcny.rr.com

I don't need MS12A sensors, I have a couple of those and they won't work for what I need.


Thanks for looking!
