Hi M.,
I definitely think it's worth buying the front-loading washer. I don't know if I save that much on utilities, but I definitely use less detergent than before and it does a great job cleaning our clothes.
You can look on sites like Craigslist and usually find people selling used ones for a lot cheaper than retail. (That's how I sold my first one when we had to move.) We found good deals at the Sears Outlet too, if you have one near you.
