What do I need?

I'm thinking about getting another CRT monitor since the one I have, I've had for nearly 6 years, and the connectors on the back especially where it plugs into the video card is very sensitive, and whenever I bump or move my monitor/computer, the screen will turn pink.

Anyway, I've never bought a CRT monitor before, and I don't know the specs that I need to look for.

I want atleast a 19" that is no more than $150. I'm a heavy gamer, so I need something that's good for that too, etc...

Also if any of you know any good deals, let me know.

Thanks.
