I love my Dew Deluxe! I think the frame is the same on the 3 of them. If the Dew Plus has disc brakes you might want to consider whether that is important to you. I like not having to think about the weather/road conditions on my commute. The discs will just work. I know some Dew riders who are very happy, though. Each step up the line = better components. Decide what level you can live with. If you google Kona Dew vs Dew Plus you should get some discussions on some of the other biking forums. The Konaworld website is also helpful.

The Kona Dew geometry does make for toe overlap depending on bike frame/shoe size. I just know it's there and live with it. You should check that out on your test ride.
