I have a lot of untreated down. Jackets, vests, sleeping bags, and quilts. This year I picked up a treated down puffy and a treated quilt. Maybe I'm skeptical and old habits die hard, but I will take care of my treated down just like my natural down. I have not intentions of pushing the limits and fully expect the treatment to wear off with age just like DWR wears off.
If it was me I'd save the $150 and read up on taking care of down equipment.
