The Printrbot is a popular printer. There are several types to choose from at prices ranging from $300 to $900. I have the Junior and love it. The Prusa i3 from Makerfarm is also a popular printer kit. You can read a bit about it on the subforum here.

Many folks, including me, believe that building a kit is the way to go. You will learn so much about how these things work and you will be much more likely to be able to troubleshoot problems. The kits are fairly straightforward to put together. Learning how to calibrate, level, etc., can be the most challenging part of the process. Very rewarding though.

Have fun,
