i had a pair of the new AT4022 omnis, and they were amazingly good for the money. the freq response curve on the 4021s looks very good to me, and may be preferable to the popular 4041s. i would not hesitate to throw down the money for 4021s at the price you are getting - sounds like a no-lose proposition. if you dont like them, i will buy them from you. the AT4051s are pretty much my favorite mics, and i have owned DPA 4011s, schoeps cmc64s, c481s and c461s, gefell m300s, etc etc over the years.
