$23 for an o-scope seems like too good to be true...

[Peter Snowberg]

I wonder how much the shipping would be?

$23 for a scope is a good deal if you ask me, no matter how limited the scope. A picture is worth 1,000 words, but a scope trace during debugging is more like 10,000,000 words.

Take care,
