Get the 43U instead of the 64U - they are virtually the same and $500 cheaper. I have it in the 46" and it completely kicks ass!

Also, get it at Visions if your getting the warranty. If you don't use the warranty by the time it ends, then you get whatever you paid as a store credit. (ie: i got the 4yr for $400. ill get that for in credit when the warranty is up)
