arduino logic analiser - has anyone tried these?

arduino logic analiser - has anyone tried these? I seen 2 one the code is given away in wiring. The other the code is in gcc. The gcc one has a gui. the arduino wiring one seems like it does not. I want to communicate to a spi port 24 bit analog to digital converter. the ads1256.

Any experiance gui's and sugjestions would be helpful.
