my ecm is giving me problems in my 91 and i'd like to replace it...where is the best place to pick one up?

those of you that are going to suggest the yard what other cars would carry an ecm that would be a direct replacement? since there were other vehicle using them there must be a decent supply out there...

 

I would get a reman unit from GM. Those left in the cars outside might have water damage and what not.

 

They can be had off eBay for $40, tested and guaranteed.
