 AFAIK, new version (probably 2.3) will come with a much wider
 bandwidth.

h.w rev 2.3 is the current version and is essentially the same spec as
V1, except that the layout is updated and the case is metal (improved
EMC). There is a separate channel for the sig gen, and other small
changes.

The schematic is here:

Note that input A/D is still done by the uP.

 Only 1 MHz bandwidth
 Verry rough sine interpretation
 Resolution to low to find spikes (Only 360 dots horizontally and even less
 vertically)

Lets be clear - its not a replacement for your Tektronix/Agilent/
Whatever, but its a dead useful tool that is full isolated, has
recording capability, is fine for audio, I2C/TWI etc. work and for
general bits  bobs...

Most importantly, its smaller than many mobile phones - loads of
reviews on Youtube.

The user interface seems OK - very mobile phone-ish (there's a
surprise!). It can ive in the laptop bag along with the USB logic
analyser ;-)

 I'm going out on a limb here and guessing that the user interface
 implementation will render it useless. Just because, when was the last
 time you bought a low-cost Chinese gizmo that had an intuitive user
 interface?

Don't sneer too much - even Teks  HPs are made in mainland China 
Taiwan ! Also, pretty much all mobiles, iThings (designed in the
UK!!), and probably 99% of everything else you use of that type.

Not to mention Tek  others rebadging Rigol scopes as their own...

Very nice! I gave away my 7904A after it developed the tick of death
- its since been repaired.

Still got a whole bunch of Tek plugins  spares but no scope for them.
Main Tek scopes are now a 2024, 2430A and 2465A. Love them.

Your restorations look more like complete rebuilds. Very smart
indeed...
