One thing to consider is this. You could buy an HDS-5 right now, then if you decide later to add the LSS-1 for down and side imaging, no problem. This will allow you to buy what you need right now, add what you want later. There are other components you can add to the HDS network also.

Yes, the color unit will do a better job showing you whats down there, and the HDS will do a much better job. Once you add the LSS-1, you'll be introduced to a whole new way of finding fish and structure. It's fantastic.
