I would not convert to 700c over tire availability. I am fairly confident there are more 27" tires on sale in America right now than 700c. Wal-Mart, K-Mart, Sports Authority, Dick's... they're all more common than bike shops and they have greater volume in stock.
I doubt that. There are more bike shops around than you might think. While Wally World might be everywhere, the others aren't found outside many metro areas. If you are near a K-Mart, etc., you will probably find a bike shop in that town too.
