I have an MSX 200 Extreme which I love. It is really a relabelled SWC 200 Extreme. It even has a big SWC sticker on it. It performs extremely well and I think it is well designed and constructed. The weak point is the Sicce pump. They can be hard to get started after turning them off. I don't ever turn off my skimmer, so it is not an issue. Other than the pump being hard to start, it is a great skimmer and tremendous value for the price. I think a lot of skimmers are ridiculously over-priced. The SWC has a good design and makes a great froth.
SWC is from Winnipeg, so you would be supporting a Canadian company, another plus for me.
Here is a link to the MSX skimmer club from RC. Lots of discussion you can peruse.

Good luck in your decision.
