jdecelles: I have the original Magic Square Prime, TE-01 Op Leader, Takara's MP-44 and the KO MP-44. I'd take any of the 3P or official options over the KO MP-44 because the KO has horrible quality control. Mine came with an arm that was falling off, missing screws from the waist and I had to take apart one of the knees in order for it to bend. I know that not all of the KOs are as bad, but since the KO goes for around $100 and TE-01 is about $90 TE-01 is usually my recommendation for an affordable MP Optimus Prime.
