Good luck with the sale. Used 150s don't sell real well since a number of people "upgraded". Just last night I was moving stuff into my basement that I've been finishing. My wife came across my VP150 and asked, "Does this go in the theater?" I sadly said, "No. I don't know where it goes."
I upgraded to a VP180 back before the VP160 came out, and wasn't willing to get next to nothing for the VP150, so I'll hang on to it for now. It just won't be doing any playing.
The VP160 does get good reviews. I am sure that you will have a really nice center channel experience with it.
