>>11253086Decide if you care about scale first. If you do, there's generally three main scales people collect and all 3 have plenty of G1 circlejerking so you are mostly in luck no matter which you choose:
1. Mainline CHUG: If you want to support the franchise and all that crap. Usually the overall cheapest (though aftermarket can get stupid like with anything else) and they sure feel like it most of the time. Mainline isn't too hard to do research for since official stuff tends to all get documented on TFwiki or whatever. There's maybe a few 3rd party CHUG scale figures once in a while but they're pretty rare honestly.
2. MP scale: Big, complex and usually stupidly expensive. Here's a decent list for MP scale. It might be missing a few but overall it's been kept really well-updated:

Legend scale: Lil guys for people short on space or like to be able to handle their toys without it being a hassle. They're also getting kind of stupidly expensive considering their size, though you'll certainly never be spending like $1000 or whatever on a combiner like you would with MP scale. Despite their small size they're also often better built than mainline. I haven't really found as good of a list for Legends as I have for MP, but a few people have put their own out so you can try looking them up.
