A timely post. I just got done building and installing 12 panels in my studio. I bought the fiberglass from ATSAcoustics out of Canada. They have a 'house brand' fiberglass that is acoustically identical to Corning 703, but costs half as much. I got 12 panels 2"x4'x2' for about $160 US, including shipping. I put another 60 bucks into fabric, and about 40 more for lumber, hanging hardware and staples. So it worked out to about $23 per panel or so.

It took me 2 weeks to build them.

The hardest part was deciding optimal placement. I have an L shaped room. The main part is 32'x19', with a bar area that's 11'x12' adjacent to the listening sweet spot. I spent 2 days using REW with a measurent mic, moving groups of panels around methodicallyl, to figure out which walls caused which freq nodes and nulls and another day (today in fact) installing them to minimize those nulls and peaks as well as possible. Well worth the effort though, things are sounding great and the sweet spot got a lot bigger.
