Hah, I started a thread the other day. I am 90% sure I'm going to try the S-120. I currently have a PSK100 and happy with it but a smaller footprint would be nice. The new S-120 really seems to go head to head with the Nyos 120 with an even better pump (IMO), the same type of twist bubble plate, and the whole thing is clear... And it's over $100 cheaper. I've spent the last 48 hours trying to find a good reason not to buy it by looking at other skimmers, and I can't find one.
