Nice to know there is a replacement. So when one of mine pop I can send it to MTH for repair. Just a little too scary reading the posting especially the "its just simple plug & play". Being retired EE I had my share of plug and plays that didn't do well in the sandbox. Because once you buy the kit and it doesn't work, its your word vs MTH, so you would end up sending it back to MTH to fix even if it was a bad out of box board, how would you prove it?
But thats just me, your mileage may vary
