I always say I'll  be picky about stuff, but I end up not being that way.  It seems whenever I do my MOC stuff, I end up selling it off!
I draw to explain to a lot of people, I only buy 1 toyline.  I cater to only 1.  I only collect one. That's GI Joe.  I don't have a budget to do Star Wars and Marvel and and and.  At the same time, I don't know what I'd do with that stuff.  People ask me to join their toy websites but I just don't in the end because I only do GI Joe therefore, I only need a few sites.  Even then, I don't visit the JBL much anymore and rely on people HERE to clue me in on what's going on.
I found quickly on the JBL, people would say, "You should totally get this, it's awesome!" and then a week later after I get it, I'm saying (in luke skywalker voice), "What a piece of junk!"
The Splitfire, Quickfire, Tigershark (or was it TigerHawk?), just a lot of stuff.  Even that Joe Snow vehicle didn't get me jiggy with it even tho I had two of 'em.  Learn to be picky?  Not quite cuz I was still buying stuff JUST IN CASE I needed it for later on.  By VvV, I was trying to be picky.  I never did get a Coil Crusher.  Never got the removable helmet CC and a few others.  
25A hit and I decided I'd get one of everything.  And then I started a MOC collection.  :\  I was game for single packs and was pretty...  relax about comic packs and even the special 7-pack sets (arctic and desert, command 3 packs, etc).  I really like the look of the single MOCs.  They look great.  I'm also staying away from the Hall of Heroes too.  Is that picky enough?  (Have yet to buy a blue ninja but that's for MOC purposes.)
Yet, I DO buy other toylines.  My reasoning?  For the DIOs!  For the stories!  Microman (Transformations), Spiderman's Lizard duder (TF), Alien Racers (TF & Island), McFarlane's CyberUnits (Island) and a few other random toys here and there.  I have a bunch of Microman figures now (as does DeathAtMidnite!) simply cuz they ARE pretty nifty.
By staying faithful to just one line, I'm figuring I can save a lot of $$$ and can always focus on the stories.
I don't know where I stand on the Resolute figures.  I like 'em but if I can make some versions w/o going that route, word.  Like Roadblock and Gung Ho.  I'm considering on how to do a Resolute version.
Movie figures...  I'll be buying mainly Joes to use.  I'd like a Scarlet is actual military garb (same w/ CoverGirl).  Their Breaker will end up my DialTone, y'know?  Staying away from the Cobra side tho.
The story AFTER DoomsDay Machine will bring in a toy or two from another line just for kicks.
