Rear Differential - sources?

I'm looking to purchase a spare chunk with 4.44 or 4.88 gears in it. I have seene thme advertised by ISC for $850, complete and outright. (I need my stock chunk for pro7) I know Mike is the best, but does anyone have a lower cost option? Better yet, anyone have one for sale?

I checked around for a while before I bought the 512 for my second Gen from ISC. All of the one's that I talked to ISC, Speedsource, Rotary Specialists, etc... all quoted me about the same when all was said and done.
