Pebele, I've a question. I'm considering taking a feat to gain a familiar, and wondered what you thought about a familiar that was a construct. The construct type is more powerful than most familiar types, but perhaps if it was toned down in other ways (not having any effective attacks, or having reduced "familiar traits" or not granting any master bonuses, perhaps?) it could still be balanced?
One idea I had was for a cool little "Da Vincian" whirlygig eyeball. Corkscrew helicopter style, with a little eye dangling from the bottom, it's basically just a recon unit/spy. The communication it has with him would be in Artooian beeps and boops, and of course, it would have a feisty disposition. If it still seems like too much, perhaps it's a living construct instead of a full construct...
Just thought I'd open dialogue on the subject in advance of level 6.
