I have a diadem that has only been used a handful of times that I'm looking to sell. I will get some pictures up shortly, just trying to see if there is any interest.
Also I was a member of the old forum, and have plenty of eBay feedback.
I think 150 shipped is a pretty fair price. It had a small leak but it was only a seal. That's replaced and it is function like new. It probably has less than a case of paint through it.
