Cabelas has a Marcum 7" unit on sale this week for $299. I have an Aqua-view 715C and to tell the truth I think the Marcum is a better unit on a dollar for dollar comparison of similar featured units. I am going to be switching to one for next season but will also keep my Aqua-view to be able to run two units. The camera is a great learning tool to see how fish react to baits, see their moods and just plain fun to watch while fishing. It's really cool watching them when they get snapped by a Jawjacker!
