There are times when you get so gripped by a concept and a project that you get possessed by it. In the Summer of 2002, I did such a project. As a builder and a modeler, I felt that t was some of my best work ever.
Back then the new Chaos Space Marine codex came out and there was this new giant unit: The Defiler. No kit was available for it at the time. So armed with a huge bits box, various plastic, brass, and aluminum bit I set off to work.
For 4 day I sequestered myself in my garage only taking breaks to sleep and eat. Unit on the 4th day I was done. 

I put it on CMON when it was just a web site, posted it on my website, and showed it off for all to see at the local hobby shop. Everyone loved it. 
Unfortunately, I had no home for it I had to sell my creation to help pay the mortgage that month. I sold it on eBay to someone in Hawaii. I would like to think it is still sitting there in a place of honor in someone’s display case, but who knows.
I sold a lot of painted minis over the years. If someone were to ask me if there was a piece that I wish that I kept it would be this one. I would even buy this back if I had the opportunity.
There were other pieces that I got hooked into over the years but this one by far was what I thought was the best I ever built. I hoe the person that owns it appreciates what they have.

I have posted a page with more details about this project here
