I am going to get one at the end of the season this year, I just want some opinions on what I should get. I have an 18' round pool, about 8000 gallons if I am not mistaken. For such a small pool I would imagine that the size of the SWG would not have to be too large. I see them on ebay, and I am going to look into it myself, but I also would like to tap into the knowledge here if I may.

What are some of the things I should watch out for? Are there bad ones to avoid? Thanks
