Who knows a good Amazon comparison chart plugin for Wordpress

Hi, I need a plugin for wordpress which meet the following criteria:


1. Can add product images
2. Auto update price and availability if it can
3. Custom fields (columns) can be added


Thanks for any suggestions!

I know Price Tapestry offer a wordpress plugin and a standalone script. I have both but dont use either. I plan on setting them up again soon as the developer has released a new update for niche related websites.
