I can't tell you much about the 800 or the 1100... But i do own 2 957c's and a 997c. I picked 2 8" versions over one 11" because with humminbird, you can't have more than two modes displayed at once(except for the new down imaging). I mounted two 900's at my dash and run them as fallows.
When driving at speed:
I run full screen map on the 997 because the si transducer doesn't like speed very much and full screen sonar on my 957. this gives me a large screen map which is nice trying to keep my boat safe in the dangerous St. Lawarence river.
When exploring or trolling:
I run split map/sonar on the 957 and split SI/DI on the 997.
It might cost a little more, but the redundency is worth it. I don't think you can go wrong with any humminbird product. Thier service is second to none, and they're really easy to use.
I think I'd prefer two 700's over one 1100 any day. just remember the interlink if you choose to buy two units.
