Now that flat-screen TVs generally cost considerably less than a Kia (a couple of years ago, they were in the Lexus range), you're thinking that maybe maybe you need to buy one. Walk into Harvey Electronics and you will buy one. The high-end audio-video stores have been transformed into shrines to the pulse-quickening art of hang-it-on-the-wall home cinema. The spacious midtown-Manhattan flagship has over twenty flat-screen TVs on display, and unlike most other electronics retailers, Harvey stocks all the biggies: Fujitsu, Sharp, Sony, Bang & Olufsen, Runco, Marantz, Pioneer, and Panasonic. You can pick up an exquisitely designed thirteen-inch SharpVision LCD Aquos for just $1,000, or dream big (really big) and walk out with an HDTV-ready 61-inch Runco PlasmaWall (the largest unit on the market) for $29,995. Harvey now in its seventy-fifth year does expert installation, too.
