Sony KV-34XBR910 australian model question

Australia has two versions, the KVHX32M31 and the KVHR32M31. They differ by $700, the difference being one has the memory card slot, super fine pitch, and DRC-MF V1 (DRC 1250, DRC 100 & DRC Progressive - whatever this is) and one doesnt.


I was interested in the cheaper one, as im not interested in the memory card slot, but does the lack of super fine pitch and DRC make much of a difference?
