I bought the behringer b1 and let me tell you, save your money. i was really new to recording and the guy at the local mom and pop store didnt know anything about mic's and he ended up selling me that piece of crap. It's not that its such a horrible mic, you can get alright sounds out of it, its just that for the money you spend you could be getting better mics. I wouldnt spend over 30$ for that mic. If you dont have an sm-57 i would recomend getting that for a little less money, if you dont already have one.
If you need further convincing just do a search on it here. I have seen few good reviews by people who have used it here.
