I'm a big fan of blind bag/box/whatever toys. They trigger whatever chemical in my brain that also responds to tearing open a fresh Magic booster pack. The down side to most blind packaged toys is the price. $4 or $5 (and up) just to pull the same figure I pulled twice already? Nah.
That's why I was a big collector of the Zerboz super hero micro figures. At a buck a pop, I could grab a handful and feed the need. These Thomas and Friends minis are definitely next on my collect list. My son is a huge Thomas fan and it has slowly infected me as well. And these are just $1.49 a piece and available at Walmart. With over 70 different designs like metallic colorways and superhero engines there's plenty to keep a collector hunting.
