Ben,

Don't get this wrong. First, I would love to buy a good machine for <
$1k :-) so if you manage to create such a beast drop me a line. 

I'm just trying to point out that you should not underestimate this
project and that so far the useable offers (here in europe!) start at
about $2k.

So, good luck for your project and keep us up to date with your
progress.

Markus
