I just purchased the 598 ci hd si combo a couple of weeks ago off e-bay for 699.99. I have been waiting for some time for Humminbird to make one that was a little cheaper in price. Had it out last weekend for four hours, all I wanted to do was ride around using the different views down imaging, side imaging and snapshot. The side imaging is worth the money. I am very pleased with this unit. The only thing to make this unit better is larger screen, i did not want to spend any more money.
