The rode NT4 is considerably cheaper on Ebay...
I also happen to have one I would sell... cheap...
But, I'll be the first to say that I am not a big fan of it. Doesn't have clarity in the highs. It does work decently for nearfield recording, which is prolly what you're doing, right?
Seems to me that it would be a better idea to just get some C-1000s or something instead. At least you can change configs that way.
