[fovea1959]

looking at buying myself a cheap portable scope for use when teaching and troubleshooting a bot. Was originally thinking about eBaying an old HP or Tekt, but buying one sight unseen is giving me the heebie-jeebies.

Keep seeing some of the ARM based scopes (agptek, jyetech, others): does anyone have any experience with anyone of these? Should I bypass these and just get an OWON or something similar?

Requirements are 2 channels, < $200, no PC needed, fast enough to watch PWM outputs going to servos and/or motor controllers, ability to trigger (as opposed to freerunning).

(or does anyone have a good working HP or Tekt looking for a new home?)
