Well, for the time being the 1000 units (with 1.00 firmware) are still available at places like http://ps2modchip.com/search.php?page=1g for ~
$205 US only. However, I've heard mixed feedback from that shop so perhaps it is safer to pay more and grab one off E-Bay if ya can't wait for a 1.50 unit solution. Personally, I'm waiting as I don't think it will be too long.
