My two bits. Plan A would be to go with the 25 watt unit, take the $100 savings and add another 50 to 70 dollars to it and look for a used 160 watt solid state PA. These 10 to 25 watt in, 160 watt out amplifiers typically go for about $150 to $170 used and that then gets you into that nice 150 watt power range. 73, Jon W0ZQ
