Hey all, I've been waiting on the hobbyist 3D printing scene to jump in on buying a system; this is really more of a "do it for fun" purchase for me. I generally dabble in robotics and hobbyist electronics, mechanical engineering, physics, etc. I've built computer systems since I was 9 years old, and I am very proficient in everything tech, although programming is definitely my achilles heel. Mostly I want a 3D printer for building my own parts, or general creativity on projects I am working on. I waited last year to make the leap into 3D printing since I didn't really see the cost-to-benefit ratio that good. Now a year later, there are many new options right around my budget of $800~ or less.

Here is my criteria:

-Prebuilt system with customer support & user forums / support
-Decent sized print area (8 x 8 x 8 approx)
-Auto-leveling Hot bed
-Compatible with a variety of exotic filaments
-Modifiable hardware/software for expandability and tinkering
-Dual extruder (or at least expandable to dual)
-Easy to work with extruder system (I'm not too knowledgeable about this part of the machine)

Ideally it would be a printer that I can get someone soon, within a month or so, and well documented. After some research on what's available (or soon to be available), I've narrowed down to these few systems (but feel free to add on to this list for me) in no particular order:
