Just had a look on their website.
Almost all products are "out of stock".
Hackaday sold it for a while, but it seems that a lot of products are dissapearing from Hackaday and they might be phasing out the "shop" on their site.
From what I've heared DSlogic has modified the (old) Sigrok / (Pulseview) source a lot and in ways that are almost impossible to port back.
For a logic Analyser I use the cheap (EUR 5) "24m 8ch" boxes from Ebay / Ali / China with Sigrok & Pulseview. (Any Cypress Cy7C68013A development board will do).
These EUR 5 LA's are plenty for debugging microcontroller stuff such as SPI UART, RS485 and a lot of other serial protocols. I've even captured low speed USB with that box and Pulseview has decoders for it.
A general development board for the Cypress supports 16 channels, but does not have the extra input protection that the logic analyser boards have.
I will gladly buy a "better" logic analyser, especially if it is oficially supported by Sigrok and it means pushing some money in their direction.
