When my Intex filter/pump died I found a great replacement for about $250 at Amazon.com. I figure it will pay for itself in not needing to buy lots of Intex filters in 2 years and it works so much better.

Be warned that the suction is so strong that it collapsed my almost clear Intex vacuum hose and hose to the skimmer. I am now using stronger hoses.
I was a little disappointed with how the whole system is held together. Only the motor/pump part is firmly connected to the base plate. The filter and debris basket are primarily held on by the pipe connections. There is a bracket under the filter cylinder, but it is not firmly connected.
I had a minor leak with the filter top. The manufacturer sent a replacement filter body with no hassles. By the time the replacement arrived, the leak had slowed so much I haven't bothered to swap in the new body yet.
I am very please with this. I only gave it 4 starts because of the less that great connections between the parts.
