Wow, just spent 4-5 hours reading this thread. I finally got to the end, so now I can jump in here. I'm starting my kit in the morning. I have a ZDZ 80RV that I was going to use and still may do so. I would rather use a DA 50, but will be lucky to afford a G-62 if I buy another engine.
Steve, I was going to suggest the Electro Dynamics light system. I have this system on my Dave Patrick PA-18 and it works great.

Anyway, I'm going to use this thread for info as there is allot of good stuff here.
Thanks, Mark
