I'd have appreciated an X700 whose electronics didn't die young. I just pitched one newer than several Nikon FE, FG, and F3 bodies that are still going strong. I bought this last one cheap but won't be bothering with another.
If it isn't too late to retrieve it, the problem might have been a bad capacitor, which is very cheap to repair. The X-700 is notorious for this problem, but the fix is easy and cheap.
