Why is someone who is asking if they can sing using a $3000 microphone?
I don't understand this.
2 OP did not ask whether he could sing or not.
'Advice' may mean singing. And may mean some other aspect of recording.
This is posted in the "can I sing" sub forum, which was created a couple months ago after much hassle. I was going to say I misunderstood, but I don't think I did. Posting here suggests vocal comments. People don't typically ask if they can sing using one of the most expensive microphones around.
Just to clear that up
I'll continue with my numbered points, shall I?
1 It is not unknown for new members to post in odd forums. We don't need to assume too much from where something is posted.
2 It is always safest to deal with a request on face value, rather than making assumptions.
OP's question was "any advice?" The obvious and first response is a clarifying question: "What would you like advice about?" Stuff about how expensive a mike is has no relevance until further context is given.
Maybe you should give him advice on his singing and not worry about his microphone.
