Actually, I think there are 2 remasters of "Let's Dance." I think EMI remastered Bowie's 80's catalog in the mid-90's (with some bonus tracks) shortly after Rykodisc did his earlier stuff. Then Virgin released a new 24 bit remaster a few years ago.
I've only heard the original CD version of "Let's Dance" (and not recently) so I can't speak to the quality of any of these.
