Very nice Trainboy, a very useful tool indeed. I have one of these too along with a Flexable Shaft Rotary Tool. I like the Dremel Cordless for ease of use but if you plan on using it a lot I would recommend buying a second battery as they wear down fast and it drains when not in use so when you want to use it after a period of time the battery is dead and you have to wait for a recharge. I always keep one in the tool and one in the charger ready to go because I can't stand having an idea and want to use it quickly only to find its dead.
