Cool, glad to hear it. I'm new to pyro, but am rather curious. (Incidentally, if
anyone can point me to notes on whether tech pan plays well with pyro, I'd love to
know). Sounds like an excuse to build another processor. As you'd suggested, making
a slot processor yourself isn't terribly difficult, just takes a couple hours on
each of a couple weekends. For the curious, here is a link to a writeup on how I
built mine. No drains (turkey baster) or water bath, but simple for room-temp.
(Built mine with the goal of b&w paper development w/ reduced setup, teardown)

Thanks for the info, hope your neck releases and the sensation is restored!
