USB DSO aka PC oscilloscope recomendations

[billbo911]

Hello all you gadget geeks!

I'm looking into purchasing a USB attached oscilloscope. These are sometimes referred to as USB DSO, or PC oscilloscopes.

Regardless of what you call them, they perform the data acquisition that is then sent to a PC for measurement and display.
I already own an ancient analog Tektronix scope without storage. I's big, heavy and does not allow post acquisition analysis.

The fact that I am a tight wad also means I would like to keep the cost down, way down!

So, I'm looking for recommendations.

Does anyone own either of these two, and would you buy it again?

Are there other USB DSO's you might prefer to these in a price range that is not too much higher?
