I have a Solidoodle 3. After a problem with a clogged nozzle and trying different build surfaces (glass plate + hairspray for adhesive) I've had a long run of successful prints (ABS only). I've printed a set of Prusa i3 parts for a friend, for instance, and some other pretty big objects. The printer does need recalibration from time to time, especially after moving it, but it doesn't take too much time. You do have to get used to the various "quirks", play around with different temperatures for different plastic colors etc, and not be afraid to take things apart. Luckily, at least for the Solidoodle and I would assume most of the other popular designs like the Prusa or Makerbots, there's a good support community out there with tons of illustrated guides to help you with almost any problem.
