My 3 or 4 year old Summer Escapes F1000C is dieing. It cuts off after a certain amount of time. I have to turn it back on at the gfci electrical plug. As those run $130 I though maybe something else would work better for the money. I found the Intex 1500 Filter Pump for $64 and the Intex 1200 Sand Filter for $111. Is the sand filter worth it?. The timer on the Sand Filter would be nice as I usually just left the old pump running. Is the sands biggest advantage is that you don't have to clean or buy new filters? Are there any other pumps that you would recommend? What is the fomular for the size of bump you need as I may upgrade to a slightly larger pool next summer?
