Such a project requires parts that you do not find easy. Schematics is not easy to find. This is one thing that far better and cheaper to purchase.

Amen, especially high power units. They aren't as simple as they seem sometimes.

What is your application, wattage, and frequency?

you can't argue with that. :D

A 555 timer seems to a favourite of this type of circuit too. Especially to get the frequency right.

I've seen some people get a transformer out of a power supply unit and just reverse the connections of the transformer.

So with a 555 going through an amplifier, this then goes through the secondary windings instead of the primary thus getting the inverted voltage out of the primary.

Not the best way to do it, but definately the easiest.
