You could try to purchase an external hard drive case and an IDE hard drive seperately.
Here is an external hard drive case:
The following are some deals from DealOverflow on IDE Hard Drives:
Seagate ST3250823AS Barracuda 250GB 7200 RPM SATA for $115 @ MonarchComputer.com
Maxtor 200GB L01P200 Ultra Series 8MB Buffer for $70 @ Outpost.com
Basically, you put the IDE HD in the external case and you can connect the hard drive using USB 2.0 with a USB cable.
