I live in Brazil and we don't have much choices in terms of cost-efficient systems over here. I have a small room with a nice TV (Sony 36" XBR) and am looking to put a little HTIB system on it. My budget is around $500 and the best two options I found available here (after lots of searching I might add) are the Onkyo HTS770 and the Denon DHT 485XP. Feature-wise they are quite similar - I'm wondering if any of guys have tried these systems and could pitch in regarding which is the better buy.
