To those who are worried about where to store or display it, can I share a solution that works well for me? I'd always kept toys at home, but I started bringing a few to work to have on my desk. Other people showed off their eccentricities and I thought why shouldn't i? Half of me expected judgment, and I was actually surprised at how many people LIKED them. And how many students would pick them up and play with them.
Then I realised, I have a HUGE office with lots of unused shelving. It fits most of my new toy purchases, and then I eventually bring them home when I need room. But it could totally fit me a Unicron.
If you have a secure employment and casual workplace, just use THEIR space to supplement your own! Simples!
Also, for those with shed envy, consider just HOW much you'd be willing to pay out for a new cool toy .... and if you're interested in Unicron, its big bucks. So look into external storage sheds if you don't have room/space to build one at home or are renting. It's not going to be affordable for everyone, but people who were even tempted at Unicron - you might be able to find one more affordable than you'd expect.
Not that I want to be an enabler, lol
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
