I currently have a CR-10S Pro V2 and would highly recommend it. Aardvark dislikes Creality printers and he certainly has the right to do so. I however respectfully disagree. I usually print at 50 - 60mm per second with mine, depending on what I'm printing. If I am doing something that I want really detailed I will slow it down to 40mm/sec. There really isn't much difference between the 40 to 50mm/sec though. I set it and forget it so I really am not worried about speed. I can't comment on the delta's as I have never owned one. If you want fast printing they certainly seem to be the way to go. Maybe someday I will fall off my wallet and try a delta.
