Looking for a 32 Channel Logic Analyzer

[smbaker]

I do a lot of vintage computer diagnostics, and while I currently have a cheap 16-channel logic analyzer knock-off, it seems like 16 channel is just never enough. 24 channels would probably suffice, but 32 channels would be even nicer. Feature I need are:

1) 5V TTL tolerant, as I primarily work with 5V vintage computers.

2) 24 channels minimum, 32 channels ideal.

3) At least good enough to do a ~ 20 MHz CPU.

4) USB-based with decent software so I can capture a log of the logic transitions and post-process them.

I'm currently looking at the Digilent Digital Discovery. Do folks here have some experiences with this, including the quality of the software that goes along with it? Is there anything else I should be looking at?

Thanks,
Scott

I have the digital discovery; it does what it says. Waveforms is pretty good, especially given that it is free.

Self-plug, but seems to fit the bill:

I second the Intronix. It has a proper state capture mode with real hardware clock qualifier inputs, great for 8-bit micros. It's biggest drawback is the limited memory
