So, I've managed to get most of the G1 Transformers I'm after (for the moment) as Encore or TFC. The plan is to set up a four level display cabinet with;
1) Galvatron/Galvatron II (Galvatron II in cannon mode)
2) Soundwave Encore/Soundblaster Encore (Soundwave in robot mode)
3) Blaster TFC/Twincast Encore (Twincast in robot mode)
4) Megatron TFC/a version of Optimus Prime (both in robot mode for size concerns)

Now, I can easily source a Twincast, and the rest (besides prime) are already purchased. However G1 Prime has had that many reissues, and will be displayed loose, so I'm looking for advice on the best/best value options to get...

I've figured that the TFC Prime with the energon mace would be the best to go for, but I'd rather spend significantly less.

What thoughts do you guys have on the 2012 Hasbro G1 OP? It has tampographs on the shoulders, doesn't it (a plus in my eyes)? It's also significantly cheaper than some other options.

Obviously, the smokestacks are a bit of a concern, but I can deal with that. However, is there a 3rd party replacement part available?

Is there something I'm not aware of or thinking of that might offer a better solution?

Thanks in advance!
