New variant in Hulk/Fing Fang Foom Build-A-Figure series on the loose

For those of you collecting the Hulk/Fin Fang Foom BAF series, there is a new variant out there of Savage Grey Hulk. The surprise variant is Classic Hulk (pictured above) and contains the same Fin Fang Foom piece as the original.
ToyGirl and I managed to collect all 8 of the Hulk/Fin Fang Foom Build-A-Figure pieces one at a time and formed the big green dragon who now sits in our living room. The set is a little expensive at $120, but he's huge (around 15 inches tall) and I think its the best Build-A-Figure I can remember. Some of the Hulk figures I liked more than others; King Hulk and She-Hulk are my favorites, while Wendigo doesn't do much for me.
Overall I think the series has been quite popular with collectors, with the She-Hulk figure seeming to be the most popular (and valuable) based on Ebay prices. She also comes with the most important part of Fin Fang Foom (the head) so that may be part of it too.
