There are two factors in chosing a mic.

The first one is the quality.  My advice would be to stay away from the 
very cheap end of the market.  The difference between the tat made to 
go with karaoke machines and a professional product (like the Sure SM58 
already mentioned) is big.  From there on the law of diminishing 
returns applys - for example using prices from one UK supplier you 
could get good recordings with the SM58 at £68.99 ($131) or splash 
out £1679.00 for a Neumann U87Ai ($3912).  You should probably be able 
to hear the difference but I'd bet it will be less noticable than the 
difference between the SM58 and the cheap tat.

The second one is colouration.  Some mics have pretty flat frequency 
responses and others don't.  Among the better ones that don't this will 
be deliberate and suits the microphone to a particular source.  The 
SM58 is an example of one where the frequency response is deliberately 
not flat and is generally reckoned to be good for vocals.

The colouration issue is such that those in pro studios keep a 
selection of mics for recording singers and try them out to see which 
one best compliments the singers voice.  This is one reason someone 
over the internet could never tell you best mic for recording your 
voice.

The other thing worth thinking about is what the connection 
requirements are for the mic.  The output level of mics is too low to 
go into the line in on a sound card and the mic in on a consumer-grade 
(e.g. onboard) soundcard is designed for a kind of electret microphone 
not often used in recording.  A dynamic mic like the SM57 will normally 
have a balanced output but can be used on an unbalanced input with the 
necessary lead.  A condenser mic will usually require phantom power so 
you would need a mic pre-amp or mixer with this facility.

> 2. Do I need a mixer?

You may be able to get a sound card with built-in mic preamps suitable 
for professional mics, i.e. not the funny interface on a normal sound 
card for the usual electret on a stalk.  If not you will need something 
to do that job.  You can buy mic pre-amps separately or you can use the 
mic pre-amps built into a mixer.  Otherwise, as long as you have as 
many inputs on you sound card as instruments you want to record in any 
one go you don't need one.

You may find a mixer convenient because of builtin features like EQ and 
effects but bear in mind if you apply these to the signal before you 
record you can not change your mind later.  Mixing, EQ and effects can 
all be done is software too so you can capture clean tracks and then 
work out what EQ and effects you want when you go to mix it.

>         Do I need digital effects?

Some EQ will probably be useful though you may be lucky and find that 
everything sounds nice without it.  If you are close micing then you 
will probably want some reverb too.  How much of what though is a 
matter of taste.

The sound cards designed for recording are generally better than the 
ones integrated onto the motherboard.  Even knowing which chip your 
integrated sound card uses doesn't mean someone can tell how good it is 
because much depends on the quality of the analogue electronics 
surrounding the chip and how much noise is picked up from things in the 
PC.

You would definitely want a new one if you want more inputs.  Otherwise 
I'd start by chosing a decent mic and get the other things to be able 
to connect it.  If you chose the sound card with integrated mic pre-amp 
obviously you'd need to buy this straight away, otherwise you could see 
what results you get with the new mic and mic-pre/mixer and see if you 
want to upgrade.

HTH,
Steve.
