My $.02c. Eighth Nerve Adept line of products is fantastic, imo. Beyond that I don't know as I would tend to DIY them, but that is me. I think a lot of acoustic treatment stuff via retail is really costly, not bad, just steep. Eighth Nerve products that I have tried would be hard to out-do for the price via DIY methods. I personally would use that as a benchmark, if it does more than Eighth nerve for reasonable money then they might be a good offering.
