Consumer 1920x1080 displays have been available for some time now. In fact, there have been CRT's that can display 2500x2000 for over ten years, and JVC has had LCoS projectors with native QXGA resolutions (2048x1536) for seven years. Recently Sony came out with two 1920x1080 LCoS displays, the QUALIA projector and RPTV. Most recently Sharp came out with a couple 1920x1080 LCD DVTV's.
As expected they all go for a premium price, but that was also the case with 1280x720 displays just four years ago.
Even if you were only interested in a 1280x720 display, I'd suggest you 'go cheap' because display technology is improving drastically, and still has a lot of room for improvement. In addition, prices are dropping as fast as the products improve, so buying high-end now, and upgrading later will cost you a tremendous amount in depreciation.
The advantage of buying entry-level products right now is that not only are they as good as the high-end stuff from only three years ago, but that even if they depreciate rapidly, the net loss wont be much which will allow you to upgrade more often.
The more difficult question will eventually be whether or not to upgrade to a 3840x2160 display. Currently there are no plans for 4K home video which will likely keep these high-resolution displays as only commercial products, but who knows. After-all, CE companies and content providers are always looking for ways to get people to upgrade or buy more products, so I suspect at some point, perhaps in ten years, there will be a market demand that could support economical consumer level 4K displays and content.
