I was looking at sand filters on ebay. They have a no name brand filter there. The pumps that they are selling with it are a brand called pmx so im guessing that the filter is that too. I havent heard of them before and wondered if anyone had an idea or two about them.http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270577841694&ssPageName=STRK:MEBIDX:IT
