Regardless of what they go for on ebay,
If we're talking about an ecu for a 2.1 wbxr, especially the D suffix one,
75 would be the very lower end of the scale of what they are worth. Price a
new one sometime. I don't think I'd let one for for that little. 
And when you gotta have one, you really need one.  
I know the guy wants to help out his tech, but having a spare is very nice.
I wouldn't consider owning a vanagon without a spare ECU or two for it, at
least one.

they go at auction on eBay for $25-75 all the time.  if the part# has a D at
the end it is from a late model and was supposed to have been upgraded from
the early years.

What should I charge him?  BTW: he is my favorite mechanic, and has
done me a TON of favors so I don't want to stiff him.
