I've stated this earlier, but to reiterate what Darren and others have said, buy what you really want and you'll enjoy it more. I had so much Hasbro junk at one point that I had to keep some in storage, how do you enjoy that? I never saw what I had, it's like having a collection of Cd's and never listening to them. I was keeping toys that I didn't really want and keeping them prisoner! I was a victim of being a completist, I had to have the battle Droid with the white mark and the one with the battle damage , etc. etc. etc. and I didn't even LIKE the battle droids!
I've sold everything off and now I get pleasure just by looking at the few Star Wars 1/6 that I have.
They remind of my youth, a safe haven , if you will , of when the world was a different place....and I enjoy them more because I know there's no clutter.
As far as spending the money goes, I see it this way, I buy what I can afford and for me it's money well spent because it makes me happy. I can think of so many ways that I can blow my money in this world and have nothing to show for it.
Bottom line is now that I'm married and father I make my family my priority, but when I can I still buy a few items that I really like.
