Personally I would spend the extra money to get a Pentax 18-135mm WR Lens. It's much better and worth it IMO. If you wait until Black Friday you can most likely get one for a really good price. Even if the lens by itself is only discounted $100 or $150, usually you'll find a camera bundle w/ the 18-135mm WR lens that is such a great deal that you could buy a bundle, sell the camera and then keep the lens for only a few hundred after its all said and done.
Case in point, Black Friday 2013, the K-5ii w/ 18-135mm WR was $799.99. In December of 2013 you could have sold a K-5ii body brand new for probably $550, which meant if had bought this bundle, you could have ended up paying just $250 for the lens (after selling the body), which is an amazing price.
I bought this bundle and decided to keep the K-5ii and sell my K-30
