Ok sorry if its been explained before, but me and my brither want to start on transformers, but I am very confused on to where to start, seeing as there are multiple different lines I.e generations, RID and all that.

So my question is where would I start, assuming I only want can I say ? Comic based? Or cartoon based? Sorry I'm very new at Transformers. But I have NO interest in movie line like DotM or RotF, I'm interested in like the war for cybertron type or the classic one.
Any ideas? And if so are they still available? Or do I gotta trade in my arm. Also I'm a big fan of the dinobots, so was wondering if they have rereleased them? Or is it the old ones I must get, also as far as articulation goes? Is it full motion with the arms and legs for the old one? Or just basic move arm up and down type?
Sorry again for being such a "noob" lol but yea any kind of insight would help me a lot, instead of me just standnin in the toy line dumbfounded, or searching online with no results.
Plz and thank you.
