I've been reading everything I can find on the 997. Shilohred and Deerhunter have made some great posts on it, but they are several months old. I am going to get one and would really appreciate finding out "how do you feel about it after having it several months", and exactly what options do I need to get with it. I get confused with the letters after the 997. 997c, 997s, ect. I understand and drool over the "side scan", which is the main reason for getting this unit, but the options are a little confusing. I don't want to find out later that I "shoulda got that" or does it come with everything except the Nav card ($200 extra). Any help at all will be greatly appreciated. Thanks.
