redline comparison of spreadsheets

[RCK]

I use Excel 2007. Does anyone know of a product that compares two spreadsheets and shows the differences between the two (similar to the Compare function in Word)? I read about a product called Change-Pro but I'd like to get input from this group. The $500 price tag is pretty steep for something that I will only use on occasion. Thanks for any feedback and ideas.

Google something along the lines of 'compare spreadsheets free' - there's plenty out there.
