Best Hobby Oscilloscope

There is a reason that a top end Agilent scope costs $10,000; it will do certain things that a cheaper scope will not.
To learn more about oscilloscopes I recommend you check out the EEV blog: http://www.eevblog.c...g/oscilloscope/
There was also an interesting short video on checking out the clock oscillator on an Arduino at http://www.adafruit....with-fet-probe/
On the low end, I have one of these http://www.nkcelectr...pe-diy-kit.html. I rate it good value for the money, but it would never do what a Agilent would.
Also a key factor is do you want to look at analog, digital or both? For analog only go buy a good used analog only scope from a top manufacturer, you can easily get one for low dollars (way less that $100). For digital what you may want is something more than just an oscilloscope. You may want a logic analyzer (which better digital scopes will have built in or available as an option) or perhaps a protocol analyzer. The reason for this is if you are hooking something up to the SPI or I2C bus for example your are probably more concerned with "Is the proper data being sent and received at the correct time?" than "What does the trailing edge of the waveform look like?" or "is there ringing on the line?" which are also important and the kind of thing that a scope would show but a logic analyzer would not.
Hope this helps ;-)

The seller comes to my house tomorrow, to prove that it works. He lives nearby.That's good!
Have you any chance to inspect it before purchasing or is it "as-is"?
He said it works, it only lacks one button (Sweep time/div) I noticed on his photo, but that's easly replaced.
It's the same button as for Volts/div, so I just take one of them as example to the local button store

Besides, that thing's $300, another $100 more and you are in Picoscope territory, and out of the toys.
The Picoscope would be cheaper as I wouldn't have to buy the iPad
BTW: following earlier recommendations I finally went for the Picoscope and the Saleae.

For consideration. What are the limitations of one of these:

I think I'm most interested in analyzing serial comm and PWM signals to know what is going on that I can not see with a multimeter.
