From RID:
If you can find them in either the Yellow Wal Mart set or the Green Devastator set, the Build Team. Apart they're not all that much, but the combined mode is pretty badass imo. And I suggest the sets because the single packed ones come in a rainbow of ugly when combined together.
The Car Bros, at least one of each mold. They're really not
that hard to transform imo, nothing like an alt or anything. Personally, I find them sorta simple in that they're mainly shell-formers.
Ruination, because
G1 combiners are cool~
And most of all, get Scourge. He's *the best* Black Optimus Prime repaint AND character ever made imo. His oil tanker alt mode, with that sexy silver/cromed trailer really works towards his total evilness, especially since it's packed with weapons. His Cab/Truck mode looks great in black and gives him a good size and siloutte fitting of one of the Badest assed D-cons to ever roll out. And depsite being simple to transform and possessing limited joints, he's both fun to change back and forth AND can be put in some down right hot poses. Throw in his big red sword and some back lighting to get his red lightpiping going and the mold really looks like it was
meant to be evil.
From Armada:
Get a Prime, any Prime. Though many people will say it sucks, I personally like the 'Super-Pants' Prime. His truck and cab mode is the right size for my tastes in comparison to other line's Deluxe and Voyager classes, he comes with a trailer that's
actually a trailer(was never fond of "Firetruckamus Prime" myself). His main gimmick is fun and works great imo, he's got himself that classic, big ol' Prime Gun, and overall I think he's a fun toy. Though the deluxe works too.
Tidalwave, a definate buy. He's so simple, and stiff, but he's a big, lovable lug who will destroy you as soon as look at you! Seriously though, half his fun is his simplicity, because he just
looks cool standing around all blank faced and bad assed.
Hoist, or any version of this mold (Personally if I didn't already have Hoist, I'd get Longrack for the better head and BW2 nod). He's a bot who looks like he doesn't even belong in any of these lines. His minicon 'gimmick' is non-existant, infact he's packed with a Minicon that has it's own gimmick because there's absolutly no reason to attach him to Hoist. He's highly posable, easy to transform and looks good in both mode...assuming you don't mind the Giganto-arm crane (I actually like the arm).
Wheeljack, just because. So his arm articulation is wonky at best, his knees are absurdly and unnecessarily loose, and his head can't turn and for some reason only one wrist can...but dammit, he's still cool. There's something to be said for a
TF that has
never had an official repaint in anyway because there's a giant scar going right through his Autobot emblem molded into his chest.
And while all the other things I've suggested were molds I own, this one is going to be an exception.
Get Unicron. Just because he *is* Unicron. For the record, the only reason I don't own his is due to space and finacial restrictions, as he's just too big and too expensive for me to hunt down. But if I could, I would, and gladly have him tower over both my 'bots and my 'cons as he should.
Also, though not limited to just Armada, it is where it started.
Get Minicons. Lots of em. None specific as I don't bother to learn their names, but find the ones you like and just stock up. Those little things are some of the coolest TFs to come out in a long while imo. Especially the ones made with the intention of being stand alone bots.
