I have an NT 1 and am very happy with it, I have an MXL2000 and an AT4033a to compare it to. Mind you I hear really good things about the Studio Projects C1 all the time - that'll be my next purchase LD condenser-wise.
I have an old Rode NT1 and NT2 and they're both good mic's. By the way, my Marshall MXL V67G seems to get more use than the Studio Projects C1 at my small little studio.
