Hello. I recently bought a 46" rear projection Hitachi tv (model 46F510) I hear some stuff about Upconverters and or Upscalers, and I was a wonderin' if any of you folks here had any info or opinions about them. I understand they all would have their limitations, and I get that they would not appeal to a purist...but I'm just trying to improve my experience incrementally without breaking the bank...thus would like to get a device that I could attach my dvd and sat receiver to...just to get some improvement (did I say all that right..??) Any thoughts or input would be appreciated. Thanks.
