I couldn't agree with you more. I have a cousin who built two complete C-3POs in Brass. This is a wearable suit to boot. The expense was incredible, but damn does it look good.My one piece of free advice that I will stick to until I die is this: there's ZERO reason or benefit to making an all metal droid. Unless you consider saying "I have an all metal droid" reason to do it. There's just no advantage. Anyone that tells you that they are more structurally sound and robust are selling you a bill of good. To be precise, it is true that an all metal droid may be more structurally sound. HOWEVER, there are NO circumstances in the natural world where you will need a droid that rugged. in fact ,there's a counter argument to be made that the slight flexibility offered by a wood frame is advantageous, as it can manage stresses better than a metal one.
Currently we do most of our units in fiberglass, plastics, and resin. definitely build depending on your skill set. Research the heck out of it.
