I've got a bottom of the range Picoscope, and I'm very pleased with it.
This thread prompted me to search for the Hantek 6022, which seems to
cost a similar price to the Picoscope, but Picoscope has faster sample
rates and a wider range of input sensitivities, so, in my estimation,
it's better value for money than the Hantek.

But it all depends on what specification you need, and what compromises
you're willing to make, money being one of them.
