I love S3D.... I have had my FF Dreamer for less than a month and I can make ABS prints that I am quite satisfied with. PLA is a no brainer. The support structure control lets me create some pretty good parts with a fair amount of overhang. There are not too many options. There could be a few more actually. The layer controls for height, speed and temp help me out a lot in getting the print to stick and not curl. On models like this that have multiple overhanging structure that have to come together it helps a lot. I am not disappointed at all with the price/features.
