You have three options, with pros and cons:
1) HDTV
++ ease of use
++ designed for TV usage, so they excel at it, naturally
++ possible to easily go over 32" sizes
-- the good ones are usually 40" at minimum
-- might have huge input lag (so you need to know which ones are good)
-- might have poorer image quality (so you need to know which ones are good)
-- usually come only with HDMI ports (but sometimes with one analog VGA port)
2) Monitor/TV combo
++ ease of use
++ built-in tuner
++/-- as they have been made with computer usage in mind, they have fairly reasonable input lag times ON AVERAGE, but will probably lose to the better HDTVs
++/-- better on image quality when compared to an average HDTV, but worse than monitor
++/-- sometimes have DVI or DisplayPort connections, as well
-- small selection and fairly rare, and therefore hard to find stock (or reviews, for that matter)
-- jack of all trades, master of none
3) Regular monitor with a separate add-on tuner (usually PCI slot or USB port)
++ you can use your computer to capture/save the channel feed
++ if you already have a monitor, then this is the cheap "upgrade" option
++ computer monitors have a huge selection of low input lag models
-- you need to keep the computer on if you want to watch TV
-- if your OS provider changes its driver design, it's up to your tuner manufacturer to provide support
-- ...which they probably won't, as it's more lucrative for them if you purchase a new tuner, as you now have to (do you remember the
Creative sound card debacle?)
Examples of the first two:
1)
Sony KDL42W705B (still the current input lag king in HDTVs, I think) (
review)
Sony KDL40W705CBU (apparently the spiritual successor for the above?)
2)
Samsung T32E310EW
