ORM in .NET

ORM or Object Relational Mapping is a great idea! When it is implemented great, there is nothing that can go wrong. Maybe I'm lazy, but all the ORM implementations for .net are too complicated. I guess for my purposes as a CAD developer, my databases are quite simple and a much simpler version would work for me. All the ones out there just stress me out and I lean more towards writing my own, simpler, leaner version of an ORM generator. Then again, maybe I am just really lazy today and am not seeing things as simply as they are. I have read of a lot of people rolling their own implementation... hmmm...
