Well I made the leap. I purchased a Lowrance Expedition C. I haven't purchased the Navionics map chip yet but, so far I like the unit. I know its not one discussed here but, I like the electronic compass feature on the expedition.
I had it out over the weekend and this unit will not read below 1.4mph once it hits that mark it goes to zero this kind of bites. I checked the lowrance site and there are no updates for it. I will email them about this later or if anyone from lowrance reads this let me know what I can do.

Paw paw, while I was researching I saw a review about the new PN 40 that is do out in the fall. You might want to hold out for a bit and see how that one performs.

Thanks for everyone's input it was very much appreciated.
