I agree with Pro and Dan.
One other thing to consider; purchase your equipment with a wide range of venues in mind. I don't have an unlimited budget to have one amp for small venues, and another for large venues.
I personally have over-powered equipment so that I can always reduce volume levels. If you find yourself in-between venue sizes, you may find yourself underpowered.
