(Reply 2)Sorry, for double post, but the first post couldn't carry all of it.<p>As of right now, my opinion is that Full Spectrum is the frontrunner based on design, the trick to reduce cost and make it much more safer, is to promote, piece by piece assembly instead of cutting the designed in one piece. Miniature model making is a hobby that makes use of the mechanical engineer inside us, making the design at the push of a button is not only costly (because of larger overall machine) but also takes out all the fun. I would buy one, if it sold for around 700-800$, and still delivers the quality of full spectrum.
