I go way out of my way. I have 213 official CV items, and 5 unofficial ones. I've spent a lot of money on my collection, but I also really enjoy it. Not just the collection itself, but the "hunt" for something new or rare is fun also. I have to admit though, this new soundtrack collection coming out next year will be the most I've spent on any one CV item, and I'm not really looking forward to dropping that much coin on one thing. But I'm still going to do it, because I know I'll regret it if I don't.
The only thing I regret about my collection is that I don't have a place to display it all. I have a couple items out, but most of it is packed safely away waiting for the day when I can display it properly.
