Homebrew PCBs

Okay, I looked through the remainder of the posts here last night.
PHEW!!!   I only read the ones that of interest to me, maybe ten or
twenty percent, and bookmarked others that may help me acquire a
particular skill when the time comes.   Thanks, guys.

Sounds like a Proxxon drill grinder would be a superior rotary tool
for drilling PCBs than the more-easily acquired dremel rotary tool.  
So I downloaded the Proxxon pdf catalog.   I phoned the distributor to
get some leads on buying one.   Now I'm searching for a U.S.
distributor on the web.   I hope it's something I can afford.  
Comments/suggestions welcome.

The Minicraft thing looks cool, but it's pulling a bit of a price tag 
isn't it?

Looked like some were up close to 70 bucks with the xformer and only 
hit 20,000rpm. It says "special motor" & "quiet". I wonder if there's 
actual noise specs anywhere to look at.

I wonder how the Walmart deals came out for the other Alan?

Which Minicraft thing do you mean?  The  	 	 	 	
Proxxon 28510 Micromot Drill 50/E ?    It is a 40W machine.   I'd
prefer the 100W IB/E (even pricier).   I don't understand why these
tools come with six different sized collets.   I guess a collet is
nothing like a drill chuck.  Maybe somebody can explain it to me.   I
guess these rotary tools are all based on the same motor controller. 
 They all say 5000 to 20000 rpm.   Maybe the same motor too.
I am thinking I might build a levered and counterweighted "drill
press" as Stefan did.

Okay, I have cured my ignorance.   After looking at this website
http://www.efunda.com/processes/machining/mill_cutters.cfm   I now
know what a collet is.   After looking at this website, it dawned on
me that this machine can be used for milling as well as drilling.
