I sold all of my Class 3 about 9-10 years ago. I didn't buy it before it was expensive, and lost money when I sold everything. I did enjoy them at first, but the cost of feeding them about broke me. I was shooting 2500 rounds a month through my C&R Sten MkV.

I think the prices are now in the "you have to be kidding" range. People buying in now are going to have a hard time recovering their costs, because only the super-rich can afford a $25,000 converted AR15.
