interesting idea but i don't think it will fly.
i did not notice that the end of this is an add offering a good deal that seems to good to believe. like any think if it is too good to believe then it probably is. the only reason i posted this is i saw this unit advertised for $599.99. anyhow just offering up the idea for discussion. i think if i lived in a tiny apartment or if i wanted something for a motor home it might not be a bad idea but i think it would lack ppwer and precision for any real big projects.
