Sony S7700, S7000, or ??? best low cost transport?

HI all,
I've seen some threads on this, and even recently, but was unable to find the specific one I was looking for in the archives.
Sooooo....one and for all now..... :-) Your opinions please... on which of these (the Sony S7000 or the s7700) makes for the best CD transport value for the dollar, and why?
Also, if there is another unit that is as good or better then these, as a CD transport, please tell me which one that is that you recommend?
Thanks and happy listening!
John
