DepthFinder/GPS advice wanted.

I am looking at getting a combo depth finder/ fish finder/GPS.

Is one better then the other?

Is one easier to install then the other?

I have a Malibu X-Factor.....So what should I be looking for?

Let me know what you think.

Thanks to all who respond.

I use an Eagle 250 ($200) and Humminbird 383C ($400). Both are combo units and work really well. The Humminbird has a much better sonar with color display but requires a 4-5 amp power supply which adds 1-2# of weight to your boat. The Eagle 250 can be run on 8-10 AA batteries. BTW - I have a new fully rigged 10 AA powersupply with charger, pelican box and in-line fuse which I can sell you for $50. I bought it to run my Humminbird and found out it didn't have enough amps. PM me if interested.
