I am the worst frugal skeptic you ever met. I was skeptical about this for way too long. It compares to not owning a bandsaw the first 20-30 stave bows. Now Im paying dearly with bad elbows, shoulders and wrists. I didnt want my lungs to be next. Spend the money and dont look back guys. And like you said Jonathan that layer of dust on everything sucks bad, especially when you need something under it.
