Hey Mike,

Yeah, I'd call them, too. I have the PB12, and like it very much. I like being able to use it as an end table; it disappears in my room much more easily that way. I also like having a dustable, hard surface instead of having to vacuum a cloth surface on the sides of the tube. I cannot imagine needing a plus version, and I have a quite large room. You'll be happy either way, I think.
