Something else to consider would be a Allen & Heath ZED12fx. http://www.allen-heath.co.uk/zed/zed-12FX.asp

You should really state what your budget is.

In my opinion it is better to buy just a mixer w/o FX, because the built-in units usually offer poor editing. Decent FX units can be found really cheap, but offer much better quality FX with more adjustable settings.
