Don't have to jump on any trans, IF is pretty much what i buy the most, and only brand atm. And even that, i don't get them all. In fact, i am very picky. Just get what i have high desire for. Buy it like your are 8 years old, not collector I think IF also not easy to pull of. But not because of the alt mode themselves are harder to achieve than real vehicle. But due to their own bot mode. I mean their bot mode is almost perfect and little to no kibble. Compare to a more complex 3rd at MP size, these bot mode still win a lot them in term of kibble free. So it basically, you just have to look at it this way: their alt mode have a lot of kibble.
