fish finder/chart plotter/down imaging
 

I am looking to invest in one of these items looking for a lil input on a good one without going broke buying one any suggestions would be helpfull.

I use the Humminbird 798. I have 2 of them. They are a little high in price but that is because of the Side Imaging. I'm not a big Lowrance fan but my dad owns a couple. He has the elite5 DSi w/out gps and the down image is pretty awesome. What I like is that the Lowrance on DSi it shows your bait go down on the screen when drop shotting. I havn't got my humminbird set up yet to do that. If you want a big screen for a good price check out the Lowrance elite7 DSi.
