sf3000 is very expensive . if u have to buy it then i suggest not, but if you get it free then it's great . this is what you should buy in my opinion . this what i use , very easy . accurate . the cost is around 435 dollars (usa dollars )
that is nice but for that price cw got it bilt in sat finder in the cw600p for 110 and works good if you got 2 pepole its eazy one looks at tv and reads the sat as you get closer and tells you witch sat you are at
