Brianward,
I made a mook gadgeteer last game, and she worked out very well. Remember to make your gadgeteer a girl, gadgeteers suck down stamina like bards, and the only gear available early on that helps with this is female only. No experience with Dwarves though, you will want to hear from others on this.
There is an excellent guide for gadgeteers here:
