2 quick things - first of all, only a couple of those are actual stabilizers, the rest are shoulder mounts. While a shoulder mount will allow you to producer more stable video while standing still, once you walk, the video will still be pretty shaky. Only a real stabilizer (such as the one you're "very interested in", or a couple of the others on the list) will actually smooth out moving shots.
Second of all, you won't find many on this site who have experience with rigs of that sort, so I think you should try other sites - perhaps DVXUser.com or DVInfo.net. This site is primarily focused towards people using full-size Steadicam systems (which regularly cost in the $20,000 to $200,000 range) to fly much larger cameras. For small cameras and more hobbyist type work, those other two sites may help you quite a bit more.
