I don't need one, but I pledged anyway. $79 now vs $99 retail later. Pretty amazing for the price (see video). They offer an overpriced 3D printed case, but hopefully they'll release the STLs.

Pretty low bandwidth... there are other USB scopes around $100 with a lot more bandwidth. I have a 200 MHz 2-ch Hantek DSO... I paid under $300 for it, and I don't have to connect it to a computer if I don't want to.

Even my DSO-quad does better, however, with all the other stuff built in it's not a terrible value. It's basically an PIC32 dev board with some analog front-end bits.

Honestly, for a lot of DIY types, something like this is more than enough. Sure, the analog DSO is slow and only good for 500khz-1Mhz on a good day... but it's enough to see if a clock is running or use the logic analyzer for some basic bus debugging. Might be better off with something like the Saelae Logic for most people though. It seems much more common for people to want to debug on the digital side, so the LA is the more useful tool. Particularly ones that include some basic bus decoding.

Wow. Where'd you get your (new?) 200MHz Hantek for under $300? Mine cost $100 more.

About a decade ago I bought a not-working but otherwise mint physical condition 60MHz Tektronix 2215 for $75 on eBay figuring from the symptoms that I could fix it. I did so at zero cost using junk box components I had on hand.

I just recently bought a cute LCD touch screen operated DO112A ($60) to check it out as part of a plan to come up with a low cost recommended package for a self-taught basic electrons course. I won't sell the package, just recommend it and will make available on-line a speadsheet of parts for easy ordering from Mouser or Digikey to use in the associated recommended text's experiments.

This OpenScope is an even more capable multi-function instrument than the DSO11A, doesn't cost much more and has the feature that really sold me on it - wifi connectivity to allow the use of a tablet as both the touch control interface and 'scope display.

Yep, that's why I listed it as a "hobbyist" instrument. I wish I'd had anything even remotely as capable when I was learning electronics.

I got it from Circuit Specialists. It was on sale for $329 with two extra probes, pretty hard to beat.

Hah! That's where I got mine and it's back up to $419. Timing is everything.
