Ralph  They are the same price as SWC is. Marine solutions sells for like $50 less or more on most all SWC skimmers. The MSX [SWC] 250A is the most sold model and it is 50 less, 499 verses 549. They have quit carrying the cones as the price difference between them and the straight chamber one isn't worth it for the performance difference, as by most test there isn't that much diff. as the neck on the conventional model tapers to the cup.                http://www.marinesolutionsinc.com/catalog/index.php
