Help buying a pool cue

[JoeDimaggio]

I've been playing pool seriously for about 1 year and need help buying a cue stick. I already have one I paid about $150 for which I'm assuming for a medium skill level player (which I would consider myself despite not playing very long) is decent/average. What price range am I looking at for not the very best cue stick but a decent top of the line one? Should I also be buying an alternate stick for breaks to prevent wear and tear on the main one? Is there much of a difference in buying a custom made cue stick from a pre-made one? I play pool almost every day also so having decent equipment is pretty important to me.
