FansProject TFX-BT-01 Alternators/Binal Tech Optimus Prime Upgrade Set Got mine in the mail from TFSource last week. Surprised no one has done a review yet but certainly understandable with the price of it being rather high. Packaging: Gas Can-non: Transforming the Gas Can-non: Nemesis Prime with Gas Can-non: Optimus Prime with engine block extension and Matrix: While this set is quite an awesome addition to the ALT/BT Optimus Prime mold, it isn't exactly price friendly. Personally I would've been more happy about the set if it were priced at, say, $20 instead. I forgot to mention that the engine block extension in robot mode pushes the hood of the truck out a bit which is also a bit of a downer. Overall, another solid set by the guys at FansProject. Hopefully they'll continues to push out more awesome custom work!
