Cheap Sources for Barracuda/Kreepy Krawly

our Barracuda pool cleaner has finally carked it. It has had many replacement parts fitted over the years, but it is time to bite the bullet and get a new one.
Wondering if anyone knows of anywhere online or offline that sells them cheap?
I did buy a $100 'bargain' pool cleaner on ebay a few years ago, but it turned out to be a cheap imitation that didn't work at all, so I will stick with a reputable one this time.
thanks, but the prices are pretty similar to our pool shop. Will have to keep my eye out for an off season sale somewhere.
