I purchased the RX-1000 TBR after originally purchasing the RX-750 TBR a week earlier. Should have purchased the 1000 originally but thought that I could save the $100 and not miss the features. One glaring difference, well worth the cash in my opinion, is the red l.e.d display versus the black. In situations that either dictate a dark background and/ or low light the rx-1000 performs whereas the 750 becomes useless. Optically the 1000 seems clearer. The sensor also performed better. The menu features are easy to navigate for the technically inclined.
