I would not be surprised if the CM7K book is stronger and the MAX is an improvement (I can get this on my CM6K as well, sometimes?). I have not seen any reason to upgrade though. I would recommed CM6K and CM7K (when the bugs are fixed) to a new person, but not as an upgrade. Just my opinion. I have always thought (perhaps wishfull thinking) that Book upgrades, board upgrades and minor changes should be provided as download (patches or free upgrades). For me to continue to buy CM in the future, I would have to see proof (SSDF) that the engine is stronger (and in the top 5) than the previous release, better db functions at a minimum, and no CD refueling. I have taken CM 6K off my machine since I don't use it very often, and when I do, I have to insert the CD (yes, I have the patch and it works, but I do not use it that often). Just my opinion. At the price, CM is a good value, But Crafty is the best and I will stay with it. :) Best Regards, Chris Carson
