Well I dont know if these skimmers are more hype than good but I was thinking of using an erlenmeyer flask to make one. You can get a 2000mL polypropolene one for around 20-40 bucks cut the bottom off then extend it with pvc. The 2000mL is just under 7" diameter at the bottom and around a foot high. The other option is to buy a glass version that is 4000mL or 5000mL. A guy at work has one and its around 10" diameter and well over a foot high. But that would require uniseals and drilling holes not knowing if it will shatter. Plus they are very expensive but less than a skimmer would cost. Just in case you dont know what a erlenmeyer flask is (I didnt know its name until today) heres a pic. I am looking for opinions on the actuall performance of cone skimmers and what you think the feasibility of this is.
