Welcome to the forum, nice test.
I've seen one J-3 go for over $300 on another forum, a KMZ lens that I worked on for a member.
Most are still going in the $150 to $200 range. The days of the $50 J-3 seem to be over.
It's certainly possible, with patience. I picked up one for around $85 on eBay only a few months ago.
