A lot of us here have our gaming collections or toy collections or comic collections, things that might already eat into your time and money quite abit, but what is something you've either set aside or purposefully avoid, as you know that if you started into it, you wouldn't be able to stop?
A big thing for me, would be Lego's. I use to LOVE them as a kid and teen. The building aspect always draws me in and for years now I've seen a ton of cool sets. A new one I saw brought up in another thread is a Voltron lego set. That appeals to my love of mecha/robots, and it's pretty badass. It's also 180 bucks. I could go broke real fast with stuff like this.
In the same vein of building, model kits of any type would be bad. I've bought a few Dragon Ball ones, mostly because I've been able to get them for fairly cheap, and I do enjoy them, but I could go in bad with a lot of the model kits out there. Dragon Ball, Gundam, lots of anime related things would drag me down pretty quick.
