I've really wanted a magi-tech and golem specific class but everytime one rolls around it seems a wizard is just more effective. Just take all the craft feats and by 8th level you can make golems, homonculi, so on. Heck, make some beaver-themed homonculi who build you a little factory, make a magical forge with their help, and start making magic guns. Between wondrous item and magic arms and weapons you can essentially make flame throwers for the whole party with enough time.
I've yet to see an artificer that has anything over a craft focused wizard.
