2008 will be our first time at a Value (Pop), however, we have friends that only stay at Disney Values. They are a retired couple and very well to do, money is no object. The wife absolutely LOVES Pop and AS Movies and even though they could easily afford any Disney Resort, they choose Values.
We drove by the AS Values during our 2007 trip and even ate lunch at AS Music (good) and they are really neat to see, the theming is wonderful!
We stayed at SSR in 2007 and loved it. We bouncedback and are staying at Pop this year, as we could not afford SSR.
We are excited, not at all hesitant!
I would absolutely go if I were you!

If you don't like it, don't do it again! Who knows?

You may find a new place to stay from now on!
