Just wanted to share this with you guys. I bought the slim 4gb model and opted to buy the 250gb HDD from China/Hong Kong. These drives cost about 40-50 bucks depending on where you shop. Installed and checked the drive, it formats to about 228gb. I think the OEM HDD is 150.00 bucks or so. Consider the cost savings and buy on Ebay. They work with no issues. Just an FYI if anyone is buying the slim or thinking on it.
