Meters get hashed over frequently, and usually each person responding recommends the meter they use. Funniest thing.
My suggestion is to first give the types of meters a bit more in-depth thought - mostly in relation to how they meter (reflected vs. incident), what that tells you, and how the different styles match your typical shooting situations. Then add a few flash-capability, low light, and battery sprinkles - again, based on what you do.
After having "upgraded" meters a half-dozen times over the years (Westons, Gossens, Pentax spot, etc.), I finally settled on a Sekonic L-508 that does just about everything - ambient/flash, reflected/incident, zoom spot, EV, etc. The later models add other features, such as radio-slave capability, etc. Having everything in one meter is really convenient.
