I've been running an Eagle 640c for 4-5 years and haven't had any complaints. I did have to replace the GPS puck last year, the old one just quit working, other than that very happy with it. I've used several different Navionics Classic and Premium map chips in it with good results also. It does look like it's getting discontinued, may be hard to find accessories in the future or get tech support (HB wins hands down on support IMO) but the unit works well. Also, there is another thread about the Eagle 480 on sale right now, that is black and white LCD (not color) but if it works as well as the 640 it's a great deal at about $200 bucks, that one has a wider screen than the 640 too. http://www.crappie.com/crappie/fishi...480-209-a.html
