Carlos, I dont know all that much about Skimmers seeing as that I'm a rookie to them too, however... stay away from SEACLONE. Avoid them like The Plague. I've starting doing a lot of research and have asked on this site. Octopus is the way to go. Just ran into a guy at store who has been into this for 20 something years and he said that the Octopus (the 150 in particular) was awsome!
