I'm pretty happy with my MSO-19 from Link Instruments. It's only got 1
channel but it does have 8 logic lines and a signal generator. When I'm in
the field I'm carrying a laptop anyway, so tossing this thing into the
laptop bag is a no brainer. The software is Windows, and is pretty good.

It says it runs in Linux on the dangerousprototypes site.
I have a Logic 8 from https://www.saleae.com/ When I got it a few years ago
they were $149. It has linux software and has been a very nice and handy
little
tool.
That OpenBench Logic sniffer looks pretty nice though - and cheap!

I have one of those devices. I'm not satisfied with it.
First, the good: the java interface does work in Linux. And it is
pretty cheap.
The bad: almost everything else. I was particularly frustrated when I
was initially trying to debug my 1.8V<>5V level shifter & hm2_spi
driver this summer.

They are about $300.
