The Intronix LA1034 is similar, but a bit faster and wider (I think
Peter mentioned it earlier).  I've used it to debug fast I2C lines
where I was more interested in the timing.  For long captures I use an
I2C sniffer (Beagle I2C/SPI analyzer).  Then the limit for capture
size is the PC's hard disk.
