I built a cable for someone's LCD-XC last week, the parts costed me around $100, I traded him the cable I built for his pair of near mint Q701. Win! The cable was really nice, if it was sold by like.. Plussound or someone else it would've costed him a couple hundred or more I'm sure. So we both win.
It never ceases to amaze me how much money you can spend in this hobby...endless almost. Great thing if music industry is what you're in, spend freely and deduct.
