mics for metal vocals

Hi to everyone!

I had read on many forums, that which is the best mic for the recording metal vocal...Everyone said the Shure sm7b, but this is expensive for me + I must buy a preamp too. The next mic they recommended is the Shure sm58. The other side say, the dynamic mics are sucks for recordings, and for the recordings is definitely best choice the condenser mics.

hey, i started singing not too long ago, i have a crappy mic, I'm gana get a new one after christmas or so, so i need to know what to get, i scream, it varies from stuff like "tha agony scene", "as i lay dying" and "the devil wears prada", theres more but, just to give u an idea, i do a small bit of vocals, so i dont want it to be horible for that,i usually use aduacity on my pc to cover songs,
