Got my Boba Fett in the mail from BBTS yesterday. As it is my first foray into Revoltech figures, I can't really compare him to much of anything, but I do have to say I am impressed. The articulation is going to take some getting used to, but my first thought was, "I CAN POSE HIM ANY WAY I WANT, HAHAHAHA!" My second thought was, "I need to get a fancy display base and a display case so dust shall never touch him."

He's slightly smaller than the Black Series Fett in bulk and height (naturally), and has the Revoltech ball joints at pretty much every point on his body (head, double shoulders, elbows, wrists, torso, hips, knees, ankles, and pockets (!)). He also has hinge joints on his toes, the rangefinder, and on the stock of his rifle (so you can slide the handle into either gripping hand with ease).
He includes six hands (two fists, two gripping/gun, two slightly relaxed; one of each for left and right), his pistol (which fits into the holster), his ESB-style rifle, removable jet pack, and two pieces of a clear flight stand (although no base is included; does anyone know to what kind of base this attaches, because I would like to purchase one). The hands are easily switchable and most of the pieces come apart with relative ease but hold together tight (the rocket comes out of the jet pack, as do the thrusters; the flamethrower and rocket on his left gauntlet can be removed).
He's detailed fairly accurately (as far as I can tell) to his appearance in ESB, and I'm very happy with how he looks. Like I said, this is my first foray into Revoltech figures, so I can't really compare him to others in this series. Compared to the BS Fett, he's very different, but as a Boba Fett collector (my main reason for purchasing him), I'm going to be displaying him by himself anyway, so his ability to fit in with others doesn't really affect my opinion of him.
