Mixer

[matt35mm]

So, I've figured out that I need an audio mixer.  I've been looking at this one.

However, I'm mostly interested in the pre-amplification part of it.  I'm recording straight into the DV camera, but the Total Harmonic Distortion, I guess it is, is too much.  Basically, there is too much hiss.  I need a pre-amp with a low hiss to send a stronger signal to the DV cam, which is more acceptable for me.

Should I get a pre-amp, or just get that mixer?  I don't really want to spend more than $100 on this, and that mixer is $99.99.  I only have one microphone, although I suppose it is possible that someday I would want to actually mix several sources together... but for now I mainly need the pre-amp.  Any thoughts as to what I should get?
