I'm not sure how much coding would be involved or if it will work with the new rating system, but It would be nice to include a breakdown of the major factors in a reseller...
A few of graphs showing...maybe... Tech support, shipping & handling, prices, etc...that make up the overall score...
Then you can make your decision based on the different scores..
For instance.....If the prices are great and the return policy sucks....I'm not buying at all..
Just a thought in case is hasn't been mentioned......
