Does the Xi5 compare at all in any categories with the others? I'm primarily looking for spot lock with Lowrance HDS units. I like the beefy looks of the Xi5 mount but not the wireless versions. Seem wimpy. I'm adding up my wish list and I'm at about $3800 for Ghost and would be much less with a MotorGuide. In addition to other things I want, must have, my cash is flowing in too many directions.
