I'm just starting so it's a little overwhelming trying to figure out where to start and what to buy/not buy. The other night I did order/pre-order MP Optimus, Wheeljack, Tracks, Ultra Magnus, Shockwave, and Hot Rod from HLJ, and Bluestreak and Ratchet from AE. Not having anything shipped until they're all in-stock so now I'm trying to decide what to track down in the meantime. Also trying to decide whether to go with Fans Toys or Gigapower for my Dinobot needs.
Yeah tough choices but it's good to have so much variety
As for the Dinobots, I've decided to mix and match; I've opted for the figures that look closer to what I remember or believe the Dinos look/should look like. I suppose that logic extends to the other TFs I pick too.
Good luck!
