It's also worth adding that SubPress's lettered edition of Silence of the Lambs is one of the finest productions they've done. It's really pretty extraordinary. Shelving it next to Suntup's Red Dragon would be fitting in so many ways.
I absolutely keep my Suntups together ... but if I ever acquire a lettered Red Dragon, that's the one exception I might make.
(Just my opinion, of course. Jeff is right - how people shelve their books is their business.)
