I don't have nearly as many figures as some of you guys do, will probably only have a single decent sized shelf worth of ones that I'd like to display permanently, plus wifey might not be too thrilled with the idea of filling up a whole room in our as yet unpurchased next house lol
But yes, agree with the comments regarding glass shelves and direct sunlight.

The seller I had the MP-04 lined up to buy from no longer has it available for sale, but I think I've changed my mind yet again and am currently looking for an MP-01L for the reasons that it was a more recent release and is cheaper, plus don't really need the trailer as I'd like to keep it MISB... and I'd probably pick up a Hasbro MP-10 when released here to muck around with and display out of box

Oh and excuse my relative noobness but liegeprime, what are the figures in your sig pic? I want some!
