Well, two years have passed, and there now seems to be more choice out there for these devices. I found this www.debug-store.com page which has links to many newer USB-based analyzers. The best of that bunch seems to be the Janatek Annie-USB 8-Channel 500MHz pod, with clips for only £275.00 / €371.25.

As far as I can tell, nothing out there matches the combination of speed/price of the LogicPort yet, but there are several appealing alternatives which include much larger buffers and DSS capabilities.

Some updates from my original posting: The ANT16 no longer exists, but has been replaced by a very overpriced ANT18i model. The BitScope units have been updated and still look quite appealing for their scope capabilities, USB/ethernet interfaces, and native Linux software. But the sample rates are still somewhat low on those.

Meanwhile, I'm now off to hook my LogicPort back up to a dead Mk2a here and see if the clocks are functioning correctly or not.

Cheers
