I thought about becoming a DM, but I don't like the whole 'Glorified Assistant' thing.
I thought I would comment on this.
I think a lot of people who are in your situation and want to go on to bigger and better things with scuba think the only option is going the professional route, beginning with DM. I think it is great that you realize there are other options, and I wish more people did, too. If you want to become a dive professional some day, you can do that, and you will be a much better professional with the additional training and experience you are contemplating.
