Never heard of it.

One thing I'm having a hard time understanding with a lot of people -- You can have one of the most popular, flexible, solidly-built microphones of all time for under $100 - Yet, some people will be looking for a "T.Bone" instead.
I'm not aiming this at the OP necessarily, but I mean... Come on...
Will the 58 give you the best vocal sound ever? Probably not -- It was designed to be a ridiculously durable and "pretty darn good sounding" mic that you can hammer nails with and then put vocal dubs on the biggest selling live album of all time (Frampton Comes Alive) or some of the biggest selling studio albums of all time (ask Bono, who uses them frequently in the studio).
It's not a SM7b, it's not a RE20 - But if you can't get a good vocal sound through a 58, you aren't going to get a good vocal sound (and it's not the mic's fault). It's much more forgiving than most of the overly-sensitive "flavor of the month" LDC's out there (a few of which can actually sound pretty decent on sources where an overly-sensitive condenser would be a reasonable choice) and it'll last you damn near forever.
Nipping the "you use condensers for vocals in the studio" types in the bud, well, that's really for another thread. But let's just say that it's not necessarily the case (as much as the marketing guys seem to be convincing people that it is).
Get the 58 and you have a mic that you'll find in literally every single professional studio on the entire planet. Get some no-name LDC with a 3-micron diaphragm assembled by a robot in Cheapmikistan and I can almost guarantee you'll be regretting it as soon as you start developing your listening skills.
