Besides the Bird folks, does anybody have good ones and if so how much?

If you suspect yours is bad, it's easy enough to verify all the current paths with a continuity tester (many Digital Volt Meters have a setting where a sound is emitted if the current path is good). I've seen relay boards on ebay around $25 (no affiliation, buyer beware, etc). You could post a WTB in any of the for sale sections if that's the way you want to go.

There's a thread here somewhere about rebuilding them ...

I got one from someone on here in the classifieds. It cleaned up great and all circuits tested ok.
Be careful using a beeper on a digital volt/ohm meter. They will beep when you have several ohms of resistance. From the pins to pins on the relay board. all readings should be less than 1 ohm, should be almost 0 ohms. Touch the leads together first to see what the leads are reading and use that for your "0" reading.

I have a new one. PM me if you are interested.
