Good to see this thread! As soon as the rates are listed I'll be putting it into the advertisting budget.
The only suggestion I would have is to *not* do a rating type system. If one is done what will happen is that it'll turn into a mess with people trashing products they don't like (because they prefer something else) or even competitors trying to make their competition look bad. Taking a cue from Microsoft & other companies that list 3rd party vendors they simply provide a listing and let the customers decide on their own.
