Hello,
What is the best Low-end(read cheap) USB Logic Analyzer?
I was looking at the Open Workbench Logic Sniffer:

or the Logic Shrimp v1 logic analyzer:

What do you guys recommend?

Thanks!
-Tim

this would be 12$, worth a try? otherwise you get a arm dev board out of it.

I found this too:

I have a propeller board that might work.

This guys' done a review of the Salea unit

Absolute cheapest would probably be the various Cypress FX2(LP) Saleae/USBee-like clones. 24MHz, 16 channels in Sigrok-supported mode. Sample depth limited by host memory.

But what samplerate/number of channels/memory do you need? Any additional features (advanced protocol decoding, triggering, etc.)?
