This is just my opinion, but if Lowrance is the way you want to go I'd go with total scan. Run it get used to it. Do a bunch of reading on the 3D and later if you think you want or need it you can always buy it used. See a few for sale on BassBoatcentral so that tells me that some folks aren't enamored with it. Lot of money to have something your not really happy with.
