...and if you're planning to get one and are located in Europe: get it 
direct from the US, it's cheaper even after the import duties.  They 
delivered via DHL in just two days.

I have both and they are different enough to make them valuable additions to 
any arsenal.  Both are USB powered, but the Saleae Logic really wants to see 
a highspeed USB2.0 port while the Logicport doesn't care.  The hardware 
triggers and the 500MHz sample rate on the Logicport on the other hand blow 
the Saleae Logic out of the water.  But if the USB port and computer can 
keep up, the Saleae Logic can record traces for minutes, while the Logicport 
will soon reach the 2k depth of it's buffer even with the hardware 
compression for most signals.  Saleae Logic has Linux software and an SDK, 
Logicport software runs only on Windows, but still on Win98.

The last point was very important to me because I have an old Notebook with 
Win98SE that didn't get much use any more - but in combination with the 
Logicport it is now a very capable logic analyzer, even with touchscreen - 
and if I really need more pixels I can connect it to an outboard screen via 
VGA.  Now if I'd manage to find the Propeller Tool version 1.0.5, I hope I 
can run the PropScope on that notebook as well... the application runs after 
I've managed to coerce .Net 2.0 onto the notebook, but it's missing the USB 
drivers, which require Win2000/XP. :-(

You've got to love these folks: "It appear that the Logic software just 
check the Vendor ID and Produce ID, and will update the driver and download 
the firmware via USB. The VID and PID are written in the EPPROM and it’s 
easy to counterfeit."  At least they're honest.
