You can find cheap clones of the Saleae logic analyzers on
eBay. I have one I bought for under $8 including shipping.
That's for the 8-channel version. I also bought the 100MHz
16-channel version for $42 including shipping but I have
not had a chance to evaluate it yet. Here a link to it on
eBay.

For a DSO you might want to consider SmartScope by LabNation.
I participated in their KickStarter campaign and am happy
with the results. It's 2 channel, 100M Samples/second and
includes an 8-channel logic analyzer and arbitrary waveform
generator. Price is $229. Supports Mac, Windoze, Linux, iOS,
and Android. Here's their web site.

I've also seen several Hantek DSOs on eBay for under $60.
That's next on my list to evaluate. I am skeptical of their
claim of 20MHz bandwidth when the sample rate is 48MSa/s.
Here's one on eBay.

I wouldn't go that far. I trust my Tektronix 2247A more than
most cheap digital oscilloscopes. I do like having a logic
analyzer that uses an external display. I just bought an
HP16700A with 16750A & 16750B modules (up to 2GHz timing).
I'm still getting familiar with it. My previous analyzers
had built-in CRTs. The 16700A uses an external display so
you could use a flat panel. It also has an Ethernet port
and the docs suggest support for remote displays (perhaps
X windows).

My Internet of Things group is focused on DIY so it has a
bit of overlap with Synth DIY. You're welcome to join. You
don't have to be in Atlanta or a member of AJUG to join. ;)
