I am designing an elaborate steampunk mechanical marvel. I originally planned to buy used gears on eBay, but the selection was limited and the prices outrageous. Now I plan to buy a 3D printer to make functional gears and possibly camshafts. I've read your and other reviews and have narrowed my choices to Zortrax M200 (my tentative favorite), MakerGear M2 (second choice) and Lultzbot TAZ5 (which has a few very bad reviews along with its many good reviews). I have no problem spending $2000, but I want a solid machine which I can later use for other serious hobby apps. Does anyone have comments or suggestions on my choice? Thanks!
