Best 51" Projection HD TV?

Looking to buy a 51" (or something close) HD Projection TV. Looking to spend in the $1000-1400 range. Would like it to have cable card slot and plenty of hookups for my home theatre sound system. Any suggestions? Also any thoughts on buying with integrated tuner or just monitor (monitor pictures seemed to look better in stores when compared to those with tuner). I know would have to use "box" with monitor. Also can HD cable box be purchased anywhere, just the basic box (ie not a "black box"), I pay enough for cable without having to "rent" a box too.
