I use Digi-key or Hosfelt.
With a schematic for my board I saw that one pole of a two pole relay was unused so I did a lot of cutting PC tracks and rewiring to use these unused contacts instead of the burnt contacts on the other relay.
It was dumb luck and I checked it many times before applying power.
$200 might be reasonable, I've heard of a kilobuck for some of these touchy boards.
BTW, [less than 30 mV]/[more than 100 mV] across closed relay contacts at rated current means good/bad contacts, respectively.
I tested this benchmark on a blower relay that was right at the 0.1v mark and it worked (but my sample size was only one). The new relay closed contact voltage was virtually zero.
