I have a set of C02's, and I think that they are great great great mics for the price. I used them alot when I sent in my Nak's for modding, and some of the shows I taped with them turned out great! I also use them when I am taping in bad weather too, like small outdoor festivals that I don't want to use my naks.
Good starter mics. I've got a few shows that you might like to hear, taped with these mics. PM me if you want me to send 'em to you.
