Tried the free edition of the #ZDSR#screenreader because I was curious. I will say that for my use-case, if #ZDSR was fully documented in English, it competes a lot more directly with #nvda than #jaws does, runs fine in a virtual machine, and has a bunch of stuff built in that I use NVDA addons for. If it had an English website I'd probably grab a copy for the entirely reasonable price. But I'm not willing to purchase through translation.
