My T-Tech machines have a fixed vaccuum attachemnt almost touching 
the cutter.  no stray dust !

I agree that surface grinders are special machines and are protected 
well.


and I HIGHLY agree that a beginners machine, a SIMPLE drilling table 
should not cost $100.00 and should be thought of as both a limited 
machine and a experiment and also a unit that will be used to expand 
into a better one or be replaced.

I would wager that a cheap machine should do 1,000 boards before one 
felt it was worn out.  and If you do 1,000 boards, you are either old 
enought to retire or can afford to buy better stuff !.
