Predaking is impressive, an imposing giant with only a few minor size discrepencies (his head and fists looking slightly smaller than expected after seeing art of him from the show and other sources all this time.) I wish you luck in finding those parts.
I've enjoyed my Takara 20th anniversary re-issue for a while now, like all good things though it is time to let others enjoy him as I phase out my G1 collection in favor of focusing more on only what I feel would be a better fit for my collecting goals.
He's solid and heavy and loaded with personality and deserving of being in anyones collection. Have fun tracking the parts down, but don't overextend yourself for them and be aware that Re-Issues and KO parts do exist for him, so if you're only interested in vintage shop mindfully.
