Jaime,

You may want to do some research on both incident and reflective (including spot) metering. If you get a good book on exposure like Dunn & Wakefield's exposure manual version 3 or 4, used ones can be found for under $10, it will help in your decision.

A big part of the decision in which meter type is dependent upon you subject. For pictures of people and products, pegging the mid-tones is IMO the best choice and incident meters excel here. Typically incident meters give you the camera reading directly.

Reflective meters have the advantage of being able to meter at a distance. The problem with reflective metering is that it can easily trick you, the meters reading need to be translated into a usable number.

With practice both methods can do very respectable jobs.
