I have the Link, 998 and 1198. You need the ethernet switch to connect them all together if you want that. You also need the Link system of course, which comes with the new i pilot module and big remote. Ethernet switch is around $180, I pilot link is around $800. I've been having problems with my spot lock on the new link module but minn kota has sent a new module. Other than that, it's been really good, especially the goto feature where you tell it to take you to a waypoint and then spot lock there. I use that a lot.
