I own a Black Diamond and I love it! For US$115, it is a great deal. You won't regret it. Just a warning concerning Seaquest Balance or Black Diamond Back Inflate BC's: They tend to trap air. When releasing all the air out of the BC, make sure your body is almost upright, remove the inflator from its chest strap, raise the inflator hose nozzle all the way up and raise you left shoulder slightly (so that shoulder valve will be the highest point on your BC). Be gentle with the inflator hose when you raise it above your head. The older rigid hose may break. The newer softer and more flaxible hose is better. In some cases, you may want to rock your body side to side to make sure all the air is out.
