Anyone have any knowledge of or expirience with the Weipro line of skimmers? Looks like a knock off of many of the recent skimmer models. I have been considering DIY'ing one, but it looks like they can be had for pretty cheap. Even if they need a little tweaking for better performance, if they are any good at all it'd me a lot more just for the acrylic.
