Unbelievable. I repeat, UNBELIEVABLE
I couldn't agree more with those of you who have stated that for this TF fan, it has gone beyond being a hobby and is now truly a sickness.
If you really love Transformers and have a big collection and it makes you happy then great. But wow, I think he has just lost all willpower to say 'I don't need that one, I already have it.' or 'That figure is on sale but I don't really like it so I'll leave it.'
I fear becoming like this. I never want to have a collection even 10% as big as this. I love collecting Transformers but have strict rules: G1 reissue/homage ONLY. That means Encore/whatever the G1 reissue line is called at the time, Generations/Classics and Masterpiece and i only buy about 25% of what gets released in the latter 2 (I don't have space for/want to spend cash on repaints like Sleep Prime, cool though he was or any figure that isn't G1 accurate like Generations 'Blurr').
I also am constantly updating my collection. To hell with buying complete lines, if I bought any figures for this purpose, even if I don't really like the figure/character then it's getting sold and the money can be used to buy a figure that i really want. That means that my hobby whilst not being self financing, doesn't eat up all my cash.
For me it's the only way to avoid getting into a similar, albeit on a smaller scale, situation to this guy.
Good luck selling your collection my friend, keep a few of your favourites for old times sake and try splitting it up into separate lots - you've already got all the pictures, just do it - you have a much better chance of selling everything!!
