I am thinking about this myself. There are plenty of articles on the net about this but nothing conclusive. You can make more money on kindle but that's only if you are a success and market it correctly and that is HARD! You get 70% of the charge when you set your price at £3.00 which would be a dream for traditionally published authors.
Personally I am going to try traditional route first then kindle if it doesn't work. The hard part for me is the cover, you will have to take the risk of paying for a professional one if you want to come across professional yourself in most cases.
