I almost bought one of those little Dremel stands since I have a couple of the rotary tools but I've heard they are flimsy and don't work well. Is there a good low cost option or am I best off just building something myself?

Quite true, the proxxon (I use the industrial strength AC powered
model) is about 115 or so USD, and the drill stand is about 40. Not
cheap, but I've tried the Dremel and for really fine holes (say #70
or less), the proxxon certainly seems to be better. You can see the
dremel wobble. The proxxon did not.
