I have a fairly unique situation, in that I need a suction side skimming device for my basin (oversized...see my pool build http://theaustindude.blogspot.com for pics).
The poolskim seems like a good affordable option, but return side. I have no returns in my basin, as the negative edge wall is how water gets in. The plus side is that my main pool is always crystal clear, since I essentially have a HUGE skimmer in the NE wall. However, all the debris ends up in the basin, which doubles as a kiddy pool.
The dragonfly (http://www.dragonfly.com.au) seems like it could work perfectly. I have a vaccuum valve in the basin.
However, it is priced at $399US!!!! and that seems pretty outrageous. Is there anything else out there that I am missing?
