I'll throw in for the original Goblin tank from TRO 3026/3039. It's the only tank from that book that has never had a mini (Barring the APCs and that engineering... thing).
I want the Wildfire from Unbound. It's re-officialized and has an updated record sheet in 3055 Unabridged.
The Teppo from TRO 3085 Supplemental, and the Destrier/Ballista from TRO 3145 Davion. They don't need to be doorstop-sized chunks of metal, just big.
The Sokar from TRO Prototypes, bucause it's unconscionable that something that ridiculously cool hasn't been made yet.
Damn you, Jal. It's unbelievable how spot-on your calls are. I second all of the above, though I believe the Sokar was already funded under FF1.0...
I looked at units missing minis and immediately had a list of more than a dozen "must haves". So I'll just throw 1 'Mech and 1 vehicle in the ring:
Patron (
Shugosha)
Loader/Patrol/DroneMechs with copious amounts of bits to make differing variants. This little 'Mech spans four different publications (TRO 3075, TRO Prototypes, XTRO RetroTech, RS Vehicle Annex) with lots of variants and could be such a fun model.
Predator Tank Destroyer from 3145 Capellan Confederation. Maybe with a variant barrel that's thinner but longer to represent the SW model (in a nod to the BattleTechnology original).
I would be throwing considerable cash at either of these.
