I would like to purchase an oscilloscope for some of the DIY projects as well as seeing the waveform on my AC power.  Which one do you think is a good/resonably priced one?

Thanks-

Just saw this on eBay: 230170576009

Kinda high shipping to offset ridiculous price, however -- maybe ask seller if guarantee non-DOA.

There are a lot of good Tektronix scopes around on ebay, but it often takes some time to find a safe bet.  Even just 20MHz will be overkill (unless you are using tubes that really like to oscillate, like 6C45P), so I wouldn't get anything too crazy/expensive.

Be sure to search ebay for 'misspellings' of oscilliscope, that's how I got my 1ghz tektronix for the $90 opening bid.  Cheers.

Naaah....  I can manage to get a lot of analog solid state circuits to oscillate/ring above a MHz. If you're building/debugging analog circuitry, a good analog scope of 20MHz bandwidth might be considered minimal.

If your interest is primarily in looking at your mains, you should consider a line viewer which works with an oscilloscope and provides isolation from the line and facilitates looking at both common and normal mode noise, albeit constrained in bandwidth to 5MHz. I got my OneAC LV-103 off eBay for $30 and they come up reasonably often.

You have a lot of oscilloscopes today that have USB output, and a software to handle the data.
That could be looked at.

Ooooo...I like that.  It provides more functionality than just a oscilloscope.

I've been looking at this one:

I bought one of these today....

Did you ever try out your scope?  How did you like the stingray?  The brochure lists 250 kHz bandwidth, is that enough?

[ctviggen]

That should be plenty for audio signals.  Even for DACs, at 44.1KHz, it shouldn't be bad.
