Got parts from element14 today: hook probes and right-angle 3.5mm mono plug. Modded my DSO nano probes, replacing the micro-tweezer probes and the connector. Interestingly the factory probed using a stereo connector, but the mono replacement works just as well.
This along with BenF 3.61a firmware upgrade has improved the DSO nano somewhere between 100 to 1000 times.
Cheers,
Steve
