I was in a similar situation, wanting Humminbirds and not wanting to keep the Lowrance units on the new Skeeter I purchased. I also had Talons previously and felt like I wanted them again. So, I played with the Power Poles and discovered I loved them. I had Fun N Sun swap the Lowrance units for Humminbird. When all was said and done, I came out right at even. Only downside is that I still have a Lowrance trans on the stern of the boat. If you are wanting to deal with Skeeter factory, I'd tell you to call them, or go to Kilgore, to see what they can do. Super nice folks and either them or Fun N Sun will take care of you, I'm sure. It's just all part of the negotiations. Plus, the tour of the plant in Kilgore is well worth the drive. Stop at Country Tavern and make a neat day of it.
And, yep, all the negatives I've heard about the new ZX deck layout had me concerned. Fished out of the new boat now for over a month, and I love everything about it!!
