Thoughts on best fish finder?

[Bduck]

I have a Raymarine A57D that just crashed on me. I was looking around for a replacement and Cabelas has a lot of FF's on sale. I was tempted to pull the trigger on the Hummingbird Helix 10 SI but quickly noticed it was sold out. Their sale price was $599. After talking to a rep at Cabelas they show 86 sold after stock diminished and no back orders. Cabelas has a large inventory of fishfinders with a few on sale in the $300 range. Weeding thru this crop will be a decision on what you want for features.
