Quick practice PA - powered speaker and mic mixer help

[don21480]

Looking to use a simple easy mixer to accept 2 microphones and provide line out to a powered speaker for practice vocals. I have a 220 watt powered speaker with a 1/4" line input - the question is what small simple mixer to plug the 2 microphones into? Any suggestions? Small size and simplicity are primary objectives -

Any of the small mixers made by pro equipment manufacturers should be fine. I prefer Allen & Heath, but have had good luck with Mackie and Yamaha, too.
