The Panasonic SDR S150 is used at my dropzone (Germany, gojump.de) for professional camera work. Mostly tandem videos (by handycam or cam flyer). We have several of them in use and they all worked flawless during the whole season 2007.
This modell is maybe not perfect for ambitious film makers considered it's limited control options but for skydiving it's great. Make and performance are solid.
Right now is nowhere a cam with SD offering this picture quality without going HD, afaik. It's also neat lightweight.
I recommend the SDR 150.
