Probably the best RTP Delta available.
Despite a few hiccups (Mostly my own failures in learning 3D printing as this was my first printer), I really can't complain too much about it as it's done everything I've seriously tried to get it to do. I hate to use the term bulletproof, but I'd call it just that. I've had it survive unreal crashes (One of them disembodied my effector plate, and shot the old-style u-clips across the room) without much trouble. Even without having the prior knowledge of building it from a kit, I was able to put it back together every time without so much as glancing as a manual. Even upgrading it has been a snap so far, and I look forward to installing the new HE280 hotend, ball-cup arms and injection molded cheapskates (Most of which come stock these days) I've ordered. I've lost count how many times I've suggested this machine to people interested in breaking ground into 3D printing. It's worth every penny, which is not something I easily say.
