There are quite a number of rapid prototype machines that are at a price point accessable by the individual hobbyist. Here is a great article that briefly surveys this field. Note that this is a VERY rapidly changing field, expecially at the low end. If you wait a year, it will surely be more mature, though I don't see prices lowering as dramatically as they have in the past few years.
Here is a excellent and concise survey of the current crop of machines.

One machine of note was a low-price machine that was fully assembled, and not a kit like many of them. The Robo 3D, is only $600.

To me the main high spot of the review is the photo-curing resin machine by Formlabs at $3,300 USD. This is quite a price breakthrough for this technology that produces such high quality output.
Of course, the other breakthrough in recent years is that the Internet lets you use service bureau to do the print for you. Some of the sites will store your own model, and allow you to sell the design to others (Shapeways, and others). One of the office supply chains has announced its intent to offer the service in the near future (sorry, I forgot the name).
I am a bit puzzled why there is not already not a lot of E-cig (especially pipes) models being sold on these 3-D printing service hosting sites. I imagine the biggest barrier is just the CAD program itself.
