I've got one and it is ok...not fantastic, but not bad. Most people around here seem to bash the mic pretty hard as being a real dog. I have recorded a fair amount of vocals with one, and posted in the mp3 clinic, and never had any comments about a bad vocal sound.. (not performance now!!). That kinda opened my eyes up to what people hear and what they wanna hear.
Possibly I got a "good" one and the most others DID suck due to inconsisitant quality amongst the mics.
I think the package of the 2001 and the 603 seems like a fair price at $150 all over the place. That seems to put it on par with all the other $80 mics, pricewhyzzze.
