I'm getting more and more into I2C and bitbanging with faster PIC processors so I'm now looking at an affordable logic analyzer to catch those fast digital signals. That Janatek Annie-USB 8-Channel 500MHz you mentioned looks like good value for the money, especially with that deep buffer of 1Ms/channel.
I was also looking at
LAP-16128U 16 Channel Logic Analyzer from Saelig
Too slow -- 200Mhz sampling means 100Mhz max capture: not fast enough for most logic.
500Mhz sampling is really the entry point here, and the LogicPort excels at it. The Annie-USB should also be good, but dunno about the software quality there, and the price is definitely higher than the LogicPort.
The LogicPort does have *very good* software, one of the best points of which is that one can download/run it in demo mode before deciding to purchase (or not).
Thanks for the good note on the Bitscope stuff, too. Maybe I'll troll eBay looking for a bargain there -- lower price would certainly make up for a lot.
