Small diaphragm and multipattern mics are very cool, but you did say only vocals, right? I would consider something with a different sound than C-1. Have you considered Audio Technica 4040, Shure KSM27/SL, Studio Projects TB-1, CAD E-200? Of those, my choice for something different would be the TB-1. I also have my own favorite that gets no respect, AKG C2000B. A mid size diaphragm mic, the 2000 is good for up front vocals, instruments, cabs, and as an overhead, and is a real swiss army mic. I think most of the Marshall mics in your price range will perform very similarly to your C-1. Just a note on the AKG- For a little more, you can get a C3000B, which I consider to be inferior to the 2000B, and would not be one of my recomendations. Also, a used AT 3033 would be fine, if you can find one, for all the same reasons as C2000B. It's another mid-sized diaphragm wicked versatile mic.-Richie
