I'm in your shoes with my own little station, so I found these on Amazon
The 48 pack of 12" by 12" panels cost about $65. They are only an inch thick, but really did a great job of killing the reverb in my studio and I could use spray glue to tack them up on the wall with no problems.

Subject: [CRTech] Acoustical Treatment
One of our many studios has no sound treatment at all. I am pushing for installing something to cut down on the reverberation.
What do you like for a cost-effect solution? Sorry, I don't do egg cartons or carpet.
