With a $1400 budget I would buy 2 units. You could get a newer barely used HDS 9 gen 2 touch and HDS 7 touch gen 2 network them together and plus add lss 2 and you have everything. Used HDS 9 going for $700-800 and HDS 7 going for $500-600 on bassboatcentral.com. There is a pair of new lowrance 7 ti with lss 2 for $1000 shipped obo just have to keep an eye on the electronic page. For $1400 you could even get an HDS 12 gen 2 which is huge if you only wanted one unit. Just a thought but worth checking out. Lots of new and used units on there daily. Hope this helps!
