Rose, Eros, Etc...

I keep reading different stories about the Rose/Eros procedure (some good, some bad lol), and different things as to which one is better (those or Stomaphyx) but I was selected to be in one of the studies, too, and wondering what some of your stories were regarding the procedure. Stomaphyx isn't an option...I don't have $11,000 for something that may not work.  My current situation is that I'm 5 yrs out, lost about 68% of my excess weight (I am 5 ft 4 and weigh 215 now) and have an enlarged stoma...my pouch is still really small, so putting a lapband over my entire pouch to act as an artificial stoma wasn't an option for me, either.  I'm not expecting to lose a huge amount of  weight...I'd be happy to get down to my lowest post wls weight which was 190...so I'm being realistic about the whole thing.  Any stories? Is 25 lbs too much to expect?
