Hi fehgalloway,
I come back to the old question: What is it that you intend for the tools to do? In other words, how much work are you going to do, and how are you going to pay to have done?
If Warmoth is going to do your bodies, you don't need a router. If you are going to do your own necks, you might want a spoke shave.
So start at the end, and work backwards. That will give you a good idea on the tools you need, and whether a Dremel tool will be useful to you.
And yes, a Dremel tool is VERY useful for general all around tasks. Kind of like hammers, screw drivers, and duct tape.
