purgatory : you always see auctions online selling stuff always says "BID WITH CONFIDENCE" , you can't keep "hoping" , only you can determine the real worth of the product you're buying by how you feel about it. it's best you go down citymusic and try it out personally.
and like what james(soft) said, you don't need the extra mixer cos you're recording, and you'll have a "SOFTWARE MIXER" inside your PC. you'll be making a wasted purchase.
kindly read my DIY Recording FAQ. you have to understand what I typed there , cos if you don't, i don't think i can make it any simpler because I made it as layman as I could.
