indeed i was.

However i'm not sure the cheaper spindles are much inferior.
The "important" words are all there ("ball bearings, ground spindle,  
ground and hardened 3-slot collets, low runout, no tool chatter...") just  
the same as with for example the IB/E (By the way they make a version of  
that now with a VERY long 20mm throat that could possibly be much better  
for large side-loads since the bearings are probably further apart).

The thing is, small DC motors are really dirt cheap, but have you often  
seen a small "canned motor" for 240V? I rarely have and that eplains why  
the 240V tools are more expensive and larger. The 12V tools have less  
power too, which is not so important for drilling.
Also, the 30eur grinders don't have the cast aluminum front, only plastic,  
which i think is no problem.

I will probably monday go and buy one, since they cost used at ebay  
alsmost as much as a new one. I can report back then how it compares to  
the IB/E.
