PC Peripherals Advice needed for VGA TV Tuner

After a long time I wud be finally buying an LCD in the next couple of days.

Been on a 15" CRT for 8 years (wud turn 8 in exactly 40 minutes) :D

But won't be retiring it :p

I was thinking of purchasing a VGA(external) TV tuner so that I can use it for analog TV signals or from a DVD player, i.e. something which directly plugs into the VGA cable of the CRT and converts it into a TV (Like those LCD TV Tuners??)

Need advice in this regard from anyone about pricing, availability, brands and experience.
