Has anyone had any experience with dotConnect for Oracle?

We are about to take on a major project that will be using Oracle, and I'd like something close to Entity Framework to work with. It looks like they have a lot of tools that build in to VS2010 which I'd far prefer instead of using Oracle's miserable tools.

I know Oracle has been promising EF for Oracle for a while, but still only has an unsupported beta out.
