I picked up a Makergear M2 last January. I've been very happy with it, and also very pleased with the support offered by Makergear. There turned out to be a mechanical issue with my machine and once it was identified they got me a replacement quickly.
Since then it's been great, and I've printed a lot with the machine. I regularly print PETG, ABS, and PLA. I've done a little work with nylons and PC. I have not second-guessed by decision to go with Makergear once. Failed prints have been minimal, and almost always my fault rather than something I can blame on the machine.
The user community is also strong with Makergear.
I'm currently running a 35 hour or so build from PETG using a .5mm nozzle. webcam->

The curvy bits on the top of the screen is a fan duct I designed and printed in ABS - so you can see the print quality I can get from this machine. I added the dual extruder which is why it looks like the nozzle isn't working - the #2 barrel is closer to the camera.
