I don't know where to start. What is a good brand? I will be using it six days a week walking 2 to 5 miles per day. I need to stay under $1000 and I was looking at a proform for $549 but then I heard they are not reliable. I am so frustrated about this. Right now I have an old Vitamaster that is literally burning up and smoking when I walk on it for more then twenty minutes.
