I say Orb is more expensive on per roll basis.
To order a single spool from Orb for me it totals $33.46....$19.47+shipping.
To order a single spool from MakerGeeks for me it totals $24.99....they do free shipping an even a single spool.
It's my opinion that the MakerGeeks is of better quality, though not by much. Orb makes some darn good stuff.
There is also a good diff in color between the two. Orb does alot of wild colors, and many are semi-tranclucent giving finished print an awesome reflective quality. MG has colors more common..more homeish so to speak ya.
I consider MakerGeeks and Orb Polymer my main suppliers...almost never look elsewhere. I do order more for makergeeks, but I think that has more to do with me being at the point in my buisness that Im ordering 1 spool more often than 3+ spools.

So....seems like I am gonna develop my own I3 clone. I am def gonna be shooting for something with a larger print bed than the Qidi.....maybe double.
If everything works out and I can actually get one built for a reasonable price I will make it into a kit and toss it on my website.
If yall know any good sites to source the parts I'm gonna need from that would be awesome of ya to share here or send em to support@rsfcustomcreations.com
