Honestly? You probably wouldn't believe me if I told you. I'll just say that it was probably about equivalent to what it would cost to build a melamine rack that size. Like I said before though, not everyone has access to the equipment that's needed. If you DO have access to it, the time and money spent building it is well worth it.
Thanks Richard, it's probably one of my favorite things to show off that I've built. The only thing I don't like about it is it's SO freakin' heavy. One of these days I'd like to make one from aluminum.
