If you are in the UK, buy from CRT. It's a no brainer. If you are happy for your DVDO HD+ to de-interlace and scale DVD, the 80 should do you. Otherwise go for the 83. (The 80 is basically a DVD/BRD transport and the 83 adds good video processing.)

Check out the comparison page though as some differences are more subtle: http://oppodigital.com/blu-ray-bdp-80/blu-ray-BDP-80-Compare.aspx

You don't need the 83SE version - that's for folk still living in the analogue age.
