Puzzle me this!: GeekDad Puzzle of the Week Solution: Extreme Products

This past week's puzzle of the week had the most interest (as measured by solutions submitted) in all of the time that I have been posting puzzles. Thank you! Here is the puzzle as presented:
Below is a set of 2400 digits, in an 80�30 grid. Using standard "word find" rules (no wrapping, straight lines only, horizontal / vertical / diagonals are allowed, etc.) strings of 5 digits can be made, and then the digits multiplied together. Somewhere in the set of digits below is the string with the largest 5-digit product, and somewhere in there is the one with the smallest 5-digit product.

This week?s puzzle is simple: Find them.
