Yeah, I feel one needs to do that every now and then.
I used to have a lot of SW LEGO and Hasbro SW figures, but it was taking up a lot of space and I figured, I'm either going to collect one thing - in my particular case, GI Joe - really well, or just kind of half-a$$ a bunch of things. So I sold all the LEGO for a profit, the Hasbro stuff at a loss, but was able to get some really key pieces for my GI Joe collection as a result. Of course, the 25th Anniversary stuff really threw that whole plan out the door, then Sideshow Joes came along... by then I had started getting the MOTUC stuff as well, and a few Hot Toys here and there.
Might be time to skim down a little for me, too. Not saying I'm selling all that, but there are a few Hot Toys figures that don't really "fit" the themes I've got going on, and I could probably get some good money for them. When I come back from this deployment I'll probably sell my extra Pred 1 and Dutch (don't ask why I got them - but I'm kind of glad I did, now!), my exclusive Cleaner Kit Wolf and exclusive Battle-Damage P2... Not sure what else. No way am I getting rid of anything Joe-related, other than extras, or vintage SW, which I really like collecting as I love SW but collecting SW stuff as a whole is overwhelming. The nice thing about Kenner is that there's a clear end in sight... unless Hasbro releases new vintage-style figures - not just vintage packaging - which would be AWESOME, but I digress.
Anyway, I figure having just the one Pred and Dutch in my collection is enough, and the way Ebay prices are going, I might actually be able to get a mint/stickers unapplied Flagg with the dough those four figures would get me....
I like what Galactiboy has - a little of everything. I'd like to have a little shelf with maybe one or two Sectaurs (loved the big ones as a kid), a few Dino-Riders (mainly the T-Rex), the "big three" from the Super Powers line, Leoric from Visionaries, maybe Warduke from the D&D line, a LEGO X-Wing, etc.
