I didn't start out looking to get in to just 1/6. My first was probably a G.I. Joe back in the 60s, and I had others throughout the late 60s and 70s (Six Million Dollar Man, The Lone Ranger and Silver, the Marx Sir Stuart (Silver Knight) and his Horse), but it didn't really matter to me what size they were as long as it was something that I was interested in. Like the original Star Wars figures, comic book stuff, the 70s Planet of the Apes figures. Then, I stopped collecting figures for a long time (mostly due to lack of money once I was on my own). In the 90s I got back in to collecting figures, but again, size was not the issue. About 10 years ago I sold at least 1/2 of the 6" and smaller figures off (comic book figs, Aliens, Predator), but kept the ones I really liked (the Universal Monsters, Danger Girl). Got back into 1/6 (or close to it) thanks to Disney's The Little Mermaid (I know... don't laugh. I've been obsessed with mermaids since Junior High when I took a "Mythology" class, so I absolutely love that movie). I can't even count how many Ariel figures I have, and of course at least one of each of the Disney "Princesses", and some Barbie mermaids too. Got back in to more "serious" 1/6 when Hasbro came out with their classic Planet of the Apes line (couldn't believe it that someone finally made my favorite actor, in my favorite role of his -- Charlton Heston). Then, of course, I discovered Sideshow when they put out their Planet of the Apes line. Got some of the James Bond SS figs, and others from other companies (Steed & Mrs. Peel, The Old Man & Ralphie from A Christmas Story). But then I got out again for nearly a decade (once again due to lack of funds). Just recently got back in thanks to the high quality of the the likenesses (the first ones I pre-ordered were Avengers Black Widow and TDKR Selina Kyle). Just thinking about some of my favorite movies and doing Google searches led me to other companies (Enterbay, DID, etc.) and some of their figures. So now, once again due to cost, I'm selective about what I get. I'm not interested in robots or robot-like (IM), and thanks to the last 3 Star Wars movies -- which totally sucked -- I've lost almost all interest in that franchise (still holding out for a great Han Solo from the first movie, and a Slave Leia). I like figures that look like the actor that played them, or generic figures that can then be turned into something original. I don't care who puts them out as long as they look good (like the Asmus Toys LOTR line). I like the female bodies that Phicen is doing, also. For as short a time as I've been back in this, I've already found myself moving toward a middle ground of straight collecting to custom/kitbashing.
Yeah. Truthfully though I put in my first pre-order (DX11 Joker) back in June. Thus far those figures are all I've got/pre-ordered. It's still kind of a lot but they've been pretty well spread out. With as expensive as they are I'm really trying to limit myself. I'm mostly going for Nolan Batman as evidenced by my purchasing history. 
It's a start.
