Garmin has great chartplotters but their FF are not the best. If you are an occasional fishermen they will be good enough, but if you do a bit of fishing, I would opt for another brand FF. I work for a large sportfish company, the majority of our units are furuno, with Northstar and Raymarine in second. There are some Simrad and other brands mixed in but few and far between. A few have opted for big Garmin GPS's, but NO other units from Garmin, have not seen a single Lowrance installed on one of our boats. These guys are spending big bucks for top notch equipment and fish a lot of tournaments. Raymarine has some nice units that can do it all, Furuno does as well, but they will cost a few more bucks then the Garmin. I love the Garmin GPS's, but I also like to keep my electronics the same brand, so until Garmin can build a decent sounder, they will never see my boat. Northstar builds one of the best GPS units and their finders are good, but they are pricey. Decide whats more important to you since you are on a budget, a sounder or a gps. Then buy a unit that satisfies your priority and can also do the other but maybe not as well. Just remember you get what you pay for, in the past I've tried to go for a cheaper unit, it always gets replaced quickly and usually with a higher end unit that stays.
