Before you make your own panels, have a look at these. Excellent price, and I have been happy the results in my listening room with four of their 2 x 4 foot wall panels.

While I have the ones that Goheelz mentions, I happen to like the ones from this company a lot better.

I second Duke: in my experience all the so called anti reverberration acoustical panels make the sound dead. Diffusors do work but in the majority of cases you should use bass traps. There is one caveat though: bass traps are bulky and you'll need lots of them to get significant reduction of room modes. If a room sucks, you'll never get good sound, even with extensive acoustic modifications.

OC703 is the material of choice for many DIY panels. It comes in 1" or 2" and maybe even thicker 2'x4' sheets, usually in '6 packs'.
You Tube (no kidding) has a couple vids on such constructions.

My plan is to treat '1st reflection' points and the back wall of my listening area. This will reduce the echo type effect while leaving the rest of the room fairly live.

Don't overdo it!
What kind of panels are you talking about? I've made some membrane panels and my only regret is that I didn't make them bigger. 6X3 instead of 4X2 would have doubled the material cost but that's insignificant to the labour and result. Membrane panels are more specific solutions for a narrower band problem.
