I'm looking for a new oscilloscope.

I'll be doing some testing of transformless AC circuits, so looking for the isolation.
Alternatively, I could look for a battery powerwed, or an isolated scope, or just an isolation transformer.

It doesn't need to be an actual handheld.

Open to all ideas, $750 is basic budget.

 

Go for an isolation transformer on the unit under test. It will protect not only the scope but also the operator. I have recently purchased a Rigol oscilloscope which I quite like.
