I recently purchased a new Yamaha Stagepas 600i from Alto Music on Ebay for $600. I think it's absolutely fantastic. This works as my PA and my main acoustic guitar amp. It doesn't have hi pass/low cut filters and the knobs seem vulnerable to damage when transporting but everything else about it is really nice.
I sold my 12 channel Carvin powered mixer and a pair of 12 inch Electro-Voice speakers for $550 on craigslist so only pitched in another 50 bucks. So far it's been a good move. Way easier to haul and set up and I think the sound quality is tops.
To testify on behalf of Carvin, that 12 channel powered mixer, PA1200, was in steady use often 3 times a week at different venues for a good 19 years or so and still worked flawlessly. It got packed up and transported every time I used it. Often either staying the night in my vehicle or getting put away for the week in my garage or front room.
Anyhow, I had been plugging into somebody else's Stagepas 400i at our outdoor worship services at a campground just about every Sunday morning this summer and I started to realize how good the 400i sounded and how simple and fast it was to set up and break down. But, I figured I needed a little more power and a mid band EQ knob so I went for the 600i. And, I'm glad I did. However, I think in most cases the 400i would still do plenty sufficient.
The newer model is the Stagepas 600BT aprox $900. BT meaning Blue Tooth. Alto Music in NY was selling the older "i" models for several hundred less. "i" meaning iPhone/iPad since you can plug in an iPhone/iPad to it's USB port. Note; it will not read/play music from an Android device. But, I simply use the 1/8" stereo jack anyhow even though I do have an iPhone my backing tracks are on a never-been-activated Android phone I got from Walmart for $65.
Prior to having the Stagepas I was using 1 of 3 other systems. All of which are sufficient in their own ways. A: The Carvin and EV set up for bigger stuff, B; 1 or 2 JBL EON10 G2 powered speakers for small to medium solo stuff. C: An older model Fender Passport 150 for smaller stuff. The Passport 150 is also around 19 years old and still working flawlessly after fixing input jacks at least once.
If you can stretch $400 USD or so I think you will be very happy with a Stagepas 400i. If they are still available.
Oh, I have also used a Kustom PA 50 at times but only on really small stuff or as a side filler. A Pair of these would likely fill your needs. They might seem cheap but are actually not bad at all. The tweeters in them are piezo but are voice somewhere around 4.5 kilohertz or higher which is a good thing as far as piezo tweeters go. They don't sound harsh at all.

Does the noise in your head bother me ?
