Rick,
You are doing the right thing. The issue (really a non-issue) was one where mouser didn't include what they should have when you got the quote. No real big deal. I think all DIYers will not mind paying a few dollars more (vice the pain and time lag of having to restart the COOP - not to mention the amount of effort you have already put into it!) Well worth a few bucks more to avoid all that agony!
Kurt
