Looks like Newegg has a 1GB Sapphire 4850 available for $239. Speeds are the same as the 512MB version, but it has a different cooling shroud. Not sure if the cooler itself is any different however.

A bit pricey considering it's reaching into 4870 territory. Hopefully the price will fall as other manufacturers start releasing their own versions.
