Luckily I am just a beginner but going to be addicted on these figures....I need to stay away from great offerings & figures. You could have the best in the market such as Batman, Joker, few Ironman, Terminator, Darth Vader and Luke. Other than that you are way too deep....Batman and Joker is the best (CRAP! I need to think about the hard earned money I spent on these figures).....well, look at the bright sight, we can sell these figures even tough will not reach profit expectation as long as we take this junks carefully.....
Trick is, only collect what you truly deeply love, not just the "fly-by-night" fads, such as every popular superhero movie.
Do you really need
every iteration of Iron Man? I don't.
I think people get into trouble with this kind of thinking.
Edit: If I can clarify a little more, just from my own experience... my 12" figure collection is quite small. It consists of HT Hellboy, HT Don Corleone, HT Spidey 3, HT DX12 Batman, HT Iron Man Mk 4, HT Wolverine, BW Scarface, BW Carlito, HT DX06 Jack Sparrow, DCD V For Vendetta and HT Supes. Hopefully this year adding the Joker, Robocop and ED-209. Maybe DX13 BD Terminator if they fix the problems with it.
These figures are either of characters I love, or movies I love, with the caveat - if it isn't REALLY good, I'm not interested. TBH, I waited 20 years for 12" figures to catch up with my personal demand for quality.
If I have to for some of these, I'll wait another 20.
I love SW. Absolutely love it. I have many, many thousands of $$$ worth of great collectibles, ranging from busts to prop replicas. For years I collected nothing BUT SW related memorabilia. But I have no DX Luke. Why? Just not good enough. I also love Indy. No DX 05. Why? Wow, have you seen the sculpt? It's poo.
I think a lot of people start to feel the squeeze because it's a figure from a movie they love, and even if it looks not great, they feel obligated to get that.
