Oscilloscope suggestions?

[hunstoer]

I’m looking for a cheap oscilloscope to troubleshoot issues with my megasquirt system.
I think i just need something that 'works', but there seems to be a lot of junk out there.
so is there any oscilloscope won't break the bank but also with decent founction.
i am currently looking at this one : https://www.sainsmart.com/tools-equ...40-40m-200m-s-virtual-oscilloscope-black.html

Meagasquirt, is that still going, a mate of mine was looking into megasquirt&spark 20 years ago.

That scope looks ok, I highly reccomend that you also use a usb isolator with it, as pc ground becomes 'scope ground, and you can blow your pc quite easily, I did this recently with a similar thing.
