We were talking the other night about 3D printers and low and behold they're selling on eBay for less than 1K for an 8" x 8" x 8", some less than $500.
Even looks like a Star Trek replicator, but I'm sure it's way slower.
Also I see consumer grade thermal imaging devices coming. Always wanted one but the $2K price tag sent me away. Thermal units now available for I phone at $350.
