I have had very good results with GIK Acoustic products, which are reasonably priced. They also have great customer service. The GIK products have made a HUGE improvement in the sound of my system.
I thought about the DIY route, but it is hard to build for much less than GIK prices. If you do go the DIY route, you may want to check out gearslutz.com and look under studio construction and acoustics forum and the sub-forum for bass traps, acoustic panels, etc., which has a lot of DIY info.
