Yamaha always good and reliable. The best small powered mixers I've used recently were Soundcraft - either the flat/conventional type or the Gigrac, which is an upright box. On board Lexicon fx, good mic pre's and usable eq. Plenty on offer s/h. Used passive speakers can be a lottery. Stick with name stuff - EV, RCF, Peavey, etc. You can get them repaired if need be.
