you definitely don't want to be using something like that microlux, the drill speed would be WAY too low.
many of the versions of the dremel drill press attachments have been wobbly and terrible for PCB drilling. Some have been OK; the trouble is making sure you are buying the right one. The model 220 drill press started out terrible (I had one), was replaced by a much better model (which I got as a replacement), and now it seems they've replaced it with another terrible version. They're all the same model number though, so if you buy one you have to be careful about which it is.
The sears/craftsman rotary tool stand that they are selling right now appears to be exactly the same as the GOOD version of the dremel model 220 that I have.

You can identify this version by the fact that the metal rod part of the mechanism protrudes from the top of the housing, and the lever attaches with a single screw. (the crappier versions have a slot cut in the lever, in which a sliding pin rides and moves the mechanism - the good one uses the much better rack-and-pinion mechanism) The one I have (dremel brand, but should be the same thing) has a number of set screws all over it, and once adjusted properly is clean enough to not break bits, though not entirely free of slop.
Another option, and a more foolproof one without a lot of wasted time shopping around, is the "PZ541 Vertical Drill Stand" from

(yes, I have one of these too) It clamps around the body of the rotary tool, so it can work with many different rotary tools - dremel and others. And, the entire thing is made of metal and is a very simple mechanism. It's somewhat more expensive, but it is compact and I never had a problem with mine.
Personally, I tend to use my (good version) dremel model 220 workstation most of the time, rather than the minicraft drill press - simply because the 220 has a larger, longer lever, making it marginally more comfortable to use.
