dario - the c3000 is rather brightish, and can do pretty well on acoustic guitar and vocal, and i would probably select it, or the c2000, over the perception line. a good pop filter is very helpful for close vocal work - i would stay around 8-10" from the mic. there are a number of pretty good choices for vocal mics in that price range. the SP B3 and B1 are very good for the money, as are a couple of the MXL models, like v67g. KEL makes some excellent, very afffordable mics for vocals. also look at what avantone offers. the AT2020 and AT3035 are both quite nice and cheap.
