You shouldn't have to apologize for wanting a reader that lets you control ebook display *without* having to manually recode and recompile the darn thing.
(I know around here there are plenty of gurus with the time, expertise, and inclination to routinely do it but out here in the real world that is *not* the first answer that pops into most people's minds, is it?)

Such readers exist and are quite affordable; certainly cheaper than Sony.
For starters, look at the Pocketbook line or some of the Bookeens.
