Brandon,
Ditto what E5Zero said. Wayne is the man.
I had the same issues I think you are having. I ended up with the HB because,
1.) All inclusive purchase. Unless things have changed from a year ago this past fall, the HB units are sold with head unit, GPS antenna, transducer, power cord, and bracket for trans and head unit. Lowrance, on the other hand, has an additional module for structure scan (SI). By the time you purchase that you're up to "in the ballpark" on price comparison.
2.) HB is pretty much "plug and play". You will have to spend time learning the features, but installation is pretty easy (hardest part is locating the tranducer for optimal return; my opimion).
