I am having my my tube replaced for the 2nd time next week under warranty. if it doesnt fix my purity problem, i am going back to where i bought the tv and complaining and will want store credit towards a different tv. this tv is a 36" JVC HDTV Tube. I have decided that i will move up to a RPTV. Possibly a smaller one $8" or smaller. What is the best i can get for my money. No higher then $1800 please. I know the sony 46" is good, right? what else is good??
