Have you guys ever seen this model kit before?
I saw someone sharing the review here:
Wonderfest Optimus Prime Resin Model Kit--any info? - TFW2005 - The 2005 Boards
which is from TFW2005

and here's a review video:
Transformers G1 Optimus Prime Resin Model Kit from Wonderfest - Resin Kit - Buy Model Kit for modelers seek for challenge.
which is from Resin Kit

I do like this kit and wondering is there a Megatron model kit in the same scale(and G1 version)?
Is it difficult to find a whole new kit now? What's the price it should be?
