You seem to be perfectly willing to deal with the proprietary Adobe DRM system, so proprietary-ness is apparently not your issue, despite your statement. What you seemed to mean was "I'd like a reader that naively supports epub and ADEPT DRM."
You say Kindle search is 'abysmal' but you don't say what you don't like about it and most of us seem to find it excellent, so again, that's a statement that's hard to offer any meaningful suggestion about.

I wouldn't mind owning a device like it seems you're asking for: Large eink display, good for PDFs, runs on AAA batts, excellent on device search and organization, broad format support.
Not sure one exists, though.
