I had a Peluso 22 251, 2247 & 2247LE, Rode NTK, Karma K58, Cascade V55, ADK A48, & an Oktava MKL2500 all at the same time. Out of all those mics I still have the Karma K58 & Peluso 2247LE. The V55 is for sale in the classifieds.
It's a toss up between the 2247LE and the K58. Sometimes one will work better than the other on a particular vocal with the K58 usually winning out on female vocals. The main thing between the 2 mics is the K58 is under $400 street and the Peluso is $1695 street. If I were just buying one mic for vocals and was on a budget the K58 would win out. Out of all the mics listed above and I could only have one I think I would still select the K58.
As always YMMV and the best way to select a mic especially for vox is to try as many as possible. Call around your area and ask studio's what vocal mics they have and book an hour or two to try them out. The same goes for the music stores as well. If it's possible have your vocals burned to a CD so you can take it home and listen in your home studio enviroment to select which mic works best for you. Hope this helps and good luck.
