the 840 pro is good but has a huge price permium, in the uk its 60-100% more than the 830. I think samsung have realised now their reputation will sell these units regardless of price.
I would avoid the basic 840 (no pro version) it uses cheaper shorter life TLC nand chips. So I would just get a discounted 830. The 840 pro whilst better I doubt will give a noticeble improvement.
