What is the metal, engineering equivalent of an erector set?

I need to make a relatively small (incorporating 1/4" rods) metal assembly. What is the metal, engineering equivalent of an erector set?
I'm designing a widget, and could use some sort of product that would allow me a lot of design flexibility. The metal assembly I'm trying to build needs to rigidly connect to some aluminum plates, have some moving joints, have other parts that are rigidly connected to a 1/4" aluminum rod (a wheel axel), give me a place to attach a spring, etc.
Is there an engineering product out there that's kind of like an erector set, and would let me tinker until I get it just right? I'm looking for something a little more versatile than drilling the hell out of thin aluminum plates and Ls and stuff, but something that is not so specialized that it won't accept thin aluminum rods and plates that I've drilled the hell out of.
Bonus points if the main support devices (lets pretend they're strut channel*, which may well be my solution) are relatively small, say between 3/8 and 3/4" in diameter.
