I think the determination of what is a good printer depends on why/what you want to make.   Most of the DIY 3D printers use rather coarse resolution FDM technology.   If you want printed parts with a good surface finish I think you have to go to other methods of 3D printing.   That being said, for the purposes of learning   FDM is a a very cost effective way to go.    Somewhere I saw a chocolate printer which might be an interesting and fun way to get kids involved and be a great item for a science fair or in some sort of booth to get peoples attention.    I'll bet chocolate printing might be a great project.

+1 on this!

I am in the process of building a MendelMax reprap printer, if you
self-source the parts, you can build one for under $1000 and they are very
good printers. The beauty of reprap is that the idea is that if you can
cobble together a halfway decent printer for little to nothing (called a
repstrap), you can then use that printer to print upgraded parts to make
the machine better, and on and on and on... it just keeps going. Check out
thingiverse.com to check out all of the add-on accessories and other parts
to print for upgrading your machine.
