Which hp pavillion laptop should I get?

My birthday is coming up in April and I usually ask for what I want in January so my dad has enough time to buy it. I want an hp pavillion laptop but idk which series to get. Dvz or dvt, or dm3? Tell me which series to start with and then which model? I want something that looks nice and also no select edition ones cuz those are very pricey. My dad is willing to spend between $500-$550 so help please!!?
