Is $100 for a used 82 Magna CDI Spark Unit reasonable?

[Rayeyoung]

Let me first apologize if this is in the wrong forum. I did look in the Parts for Sale forum and did not find any additional info.

Long story short, Honda has diagnosed my 82 Magna 750 as having a bad CDI. They replaced the coil but the front two cylinders still do not get spark. They are telling me that Honda no longer makes this part. I have looked on eBay and searched Google and can't seem to find any for under $150.00.
I have contacted a salvage yard locally that says they have a few of them and they are asking $100.00. On eBay I did find other CDI for a Honda CB 750 for $35.00.

I wanted to get your opinions before possibly getting ripped off.
Anyone have any advise on were to maybe find a new CDI or a used one for a better price?
Does anyone know if $100.00 for a used one is a reasonable deal?
Does anyone know if a different model CDI will also work on my 82 Magna?

The CDI that came off the bike has the following info on it:
NIPPONDENSO
131100-3260 - 12v


Thank you in advance, Any advise is much appreciated!

Thank you DG for the link.

Rod47 contacted me and has one available for less than what I can find here locally (thanks Rod).

After I receive the part, I will update this thread with the results.
Thanks again for your help!
