I know we covered this a few months ago, but I wanted to see if any of the new people had any sugestions.

So far this is what I am thinking.

for th sound card and mic amp (I found it for $130)

for the Mic (parts express for $50)
http://www.behringer.com/ECM8000/index.cfm?lang=ENG

For the program I am planing on demoing 2 maybe 3 and upgrading / picking my fav from there.

The sound card with preamp is a good choice.

I would suggest another mic. Behringer is poorly made, however they are decent cheap mics. I own a few Behringer items, and their quality isn't that great.
I would look into Earthworks, Rode, AKG, Studio Projects, Beyer, Oktava, etc...

I need to play with those two other programs. I've used the trial of TrueAudio RTA, I liked that a lot.

Oh, another thing is calibration. You will want the response curve of a microphone. I don't believe there are many mics with a flat curve at all frequencies (20-20k Hz).

Yeah I am pretty sure all the programs I listed have a mic / soundcard calibration.

I know the TrueAudio RTA one does. But I think it is for specific microphones... I don't remember now. I can play with it tomorrow night and give you some more info.

I just opened it up. It lets you do a mic cal and save it to file. That way you can load it when ever you need to.

Out of the mics you listed earthworks has a couple of measurment mics (the cheapest is about $600 bucks.)

I did find a few others that will work. What do you think about these?

The second is more than I want to spend, but if I can find it cheaper I might

looks good. DBX makes some good stuff. I have a freakin awesome compressor from them.

I don't know if you have a Guitar Center around you, but 9 times out of 10, you can haggle them down.

Yeah I kinda do, but its on base and their prices are way to high. Pluss they don't have much of a selection. They do have some car audio stuff, 95% of it is rockwood / pyle / and so on. They did have a JL 10W3 V1. I asked about a price and they told me all the lower the could go was 180. It was hard not to laugh in the guys face. Especially when the 10W3V2 is only around 160
