Apparently there is quite a bit of ignorance about 3D printing here. Also slashdot has become populated with too many Apple and M$ users who have "it's not ready for the consumer" mentalities.
I bought a Printrbot Simple ($300) for my son for Christmas. He and I put it together, tweaked it, and now we use it to print cool plastic stuff. He printed a rose for his girlfriend for Valentines day which she like very much. How f*^%ing cool is that? Taking a bunch of parts, putting them together to make a machine that can make stuff. It is totally fun and cool. I'm so glad I got this thing. It has given me the opportunity to give to my son what I had when I was his age with computers: the ability to tinker with tech and make something cool.
As far as 3D printing not being "standard" nothing could be further from the truth. When you order the Printrbot Simple unassembled, you get a box full of parts in the mail and nothing else. No instructions, no software, nothing. You don't need any non-standard crap. The connector is a standard micro-USB cable. The instructions are online as web pages and help is available on the forums. The software I need to run the printer and make models is already in my Linux distribution.
"sudo yum -y install RepetierHost blender" and off we go!
If you want to do some hobbyist tinkering or if you want to give that joy to someone whom you love, get a 3D printer.
