Thanks very much for the reply! There are actually 490 and bdt120 models in my country. The question is if they share the same processors with their elder brothers. Most people i asked said yes. So my last dilemma is if bdt120 and 220 share the same processor and have the same features pq-wise.
They are from the same generation and based on the same design, it looks like - with the difference being features. So they should be identical at a basic level. Here's a review of the 120.
