Monitor with TV tuner vs. HDTV: Which is better?

I’m looking to pick up a TV for my apartment, but since space is pretty tight, I’ll basically be using it as a PC monitor too. What’s the smarter move here? Should I go with a monitor that has a built-in tuner, or just stick to an HDTV with HD resolution? Honestly, I don't care much about the TV quality itself—but when I'm actually sitting at the computer doing stuff like browsing the web, watching YouTube, or working in Adobe Illustrator, which setup is going to give me a better experience?

$3500-$1233.

Honestly, it’s a way better move than squinting at some tiny little computer monitor shoved right in your face. It makes working much more comfortable—I’m sitting about three feet back—and for the price, it’s a decent enough TV.
Your eyes will definitely thank you later.
