hand held or bench oscilloscope?

Whats the opinion on a Hitachi Denshi V222 with a Thandar 2MHz Function Generator, with manuals and cables.

What is it that you're looking to use this for? From what I can gather from google this is a 20MHz dual channel CRT oscilloscope with a modulatable Z input (intensity - I've used this sort of thing in the past in place of cursive displays). Old analogue technology, with a trigger supporting TV synchronisation as well as the usual, heavy as hell, and with an aged CRT display (look for phosphor burn and adequate intensity and focus). Probably very useful for audio and unmodulated analogue video work, as well as low-end/frequency repetitive waveform digital measurement. If that floats your boat, I'd squint hard if the cost on fleabay was more than about £40.

The Function Generator - You don't offer much to go on, but likely a useful tool given the limited frequency range - good for testing audio circuits and even stepper systems for sure provided that it provides a DC offset (most do). Assuming a typical analogue job, If I was in the market for one, again, I'd hesitate above £30-£40.

If you look at the new digital chinese systems - you simply get more bang for your buck. An arbitary waveform function generator will cost about £40-£50 for entry level and will knock the socks off the Thandar, unless you need the low distortion of the analogue design that I assume the Thandar is based upon. Digital scopes just simply wipe the floor with basic entry-level analogue scopes - okay, you're looking at the numbers mentioned earlier in this thread £100-£250 entry level for PC/bench respectively, but they are simply more capable (and capable of misinterpretation!... caveat empor applies).

To put in context, I threw a Tektronix 453 dual trace analogue scope in the tip more than a decade ago. A beautiful 50MHz dual channel scope that would outperform the Hitachi, that from an electrical design was a thing of utter beauty, but just 50 years too old and from an analogue era long gone.
