Hi all. I'm from Argentina. My brother is currently in NYC, so I'm thinking about asking him to bring me a budget 3D BD player. These are the ones I found: Sony BDP-S590, Panasonic DMP-BDT220, Samsung BD-E5900 and LG BP62 (all $149.99 list price) Besides picture quality, I'm interested that the player plays nice with all kinds of video and audio formats. Also, I know all of them will be Region A, but what about DVD Regions? (I have lots of region 1 and region 4 discs) So, what do you think? Which one do you recommend? Thanks in advance. PS: Any of those brands offer international warranty?
