I just tried it and there are still some bugs. Namely, GPS does not work, market does not see all apps, video camera does not work. It is a vast improvement over the technical alpha from earlier. The next RC will address these issues and from what I hear there may even be some aspects of the Gingerbread SDK worked into it! When its ready, it will be the top rom for the DX in my opinion.
Stop using toolkits, especially with nexus devices. Learn ADB and fix problems yourself. It's not hard and can be faster then a toolkit.
