Yes CRT monitors are said to be better for games, but this was only because of the Response time that LCD monitors have where it takes a certain amount of time in miliseconds for the screen to refresh.
New LCD monitors can offer 12ms to 8ms repsonse times so you wouldn't notice any 'ghosting' in games, and even racing games, so they are getting better in quality and so are good replacements even for games in homes.
CRT's though good do release radiation which LCD's would lower and they tend to look better too since they don't bulge at the back, and can offer superior quality, especially if it has a DVI connection, and your computers video card does too (better digital interface rather than analog like VGA)
When looking for one, look for the highest response time (smaller number), the Brightness value and contrast values (Higher the better, so just check for a few to get a minimum amount and a higher amount and if you can not affford the higher one, go for inbetween)
Dead pixels are a worry, though shops have to replace them if a certain amount are sent to you, though you can ask for a replacement anyway, and it is not that common, and definetly not common enough for you to worry about them (you tend not to notice 1, especially if its somewhere in a corner for example, though shouldn't happen I know)
I hope this helps
