Well, many years later, and the Welec W2022A now has very usable third-party firmware, and a lot less noise on the signals. But I've decided to upgrade to a newer/better scope. There are now quite a few usable digital scopes with good bandwidth out there.

After a lot of reading/research, the perfectionists say to get something like a Lecroy scope, but those are horrifically expensive. In the budget category though, the Siglent brand is highly recommended. So I've ordered a 200Mhz 2-channel Siglent scope (1 gs/sec), for CAD$458+tax. The Lecroy 100MHz equivalent is more than 2X that price.

Real world reviews and measurements indicate the Siglent is the Real Deal, with actual 3dB bandwidth around 240MHz. The firmware for it has had regular updates and is working well.

Notice anything funny about the photos.. ?
