I have an Armada Unicron (two, actually, one is at my nephew's) but not HazLab. I also didn't back LioKaiser because things went a bit nuts.
The shelf didn't cost as much as it looks, a friend got me Victory Saber when things were going badly for me the first time, I later got DeathSaurus myself, using ebay funds, and did it again with the Omega Prime set, in both cases banking more than the HasLabs cost. Due to a mix of medical and home-repair issues LioKaiser got cancelled before it closed, but I still think these four make for a pretty good capstone. I'd contemplated selling Omega off right away, but for now I will hold onto it, as I was uncomfortable selling it sealed due to the QC issues, and after fixing them, I might as well see what happens.
