That's an easy question, I've only got two!

I'm with Birdie, I like to get them out of the box! With these two (above) they are in blister packs, so the contents can easily be seen. In any case, I have another copy of 4430 out of the packaging and a second copy of the older knight in that 80542 40th Anniversary Magazine enclosure.
I don't really 'do' MISB. I only buy them if I want to be certain what is in the box of a particular set (I've only done this a couple of times) or if its the only way to get hold of a complete set with all the accessories. And I prefer not to pay MISB prices if there is a good, cheaper alternative!
Actually, I don't really get the attraction of MISB collecting. May I be forgiven for swearing in church. (Great expression that Birdie, I haven't heard it before!)
