The last one I saw trade on e-Bay, about five years ago, went past $150 the day before it finally sold.
But - if you act now! There are three of the most common packages, the 50550 toggle module available for bid on eBay. There were over 50 of these modules in the typical B-205. They are labeled as "40" in the photo on this webpage on my Datatron site.
Here's the link to eBay.
