I agree DM, that's why I prefer to focus my time, energy and resources on slowly assembling, improving on, or acquiring only (what I see as) perfect representations of my absolute favorite television and film characters.
But hey, everyone has different collecting habits/views.
I have to ask your opinion though (and everyone commenting on market value), what's your take on this scenario? Say I want to sell my Rainman Dude figure (not going to happen)...I've had him since release, quite some time now, and in that time he has gone for several thousand dollars. If I needed to sell him for whatever reason (my interests have changed, I need the money etc.), would I be expected to ignore his apparent market value, and sell him at his original price tag, to avoid being considered a 'flipper?'
