Given a dremel new is $120-150 ish...

Trim routers like these:

For $119 with a full alloy body are a better bet.

As I see it, it's cylindrical so it's easier to mount, no speed control 
inbuilt so you can use a closed loop speed control on it for better 
cutting in soft stuff.  It'll also have higher rotor inertia and a 
better quality chuck.

There are a few on the market.  When I last looked there were a few 
options on the shelf at Bunnings/Mitre10 that looked good.

I was specifically thinking dremel replacements for wood/plastic/alloy 
cutting.  If you're looking for dedicated spindle ebay is probably your 
friend..

And, having said all that, my next project is going to be swinging a 
water cooled VFD spindle.  I am sooooo over the noise of brushed routers!!!

Cheers, Me.
