If I only get to pick one favourite soap opera, it's definitely "Melrose Place" that originally aired between 1992 and 1999. I first saw it as a kid and I recently started rewatching the whole series on DVD for the fourth time. I never get tired of it. What I love about the show is that it's not afraid to go over the top with crazy storylines and plot twists. Check out my "Melrose Place" DVD collection down below.
All seasons have been released on DVD and you can order them all from Amazon. However, the final two seasons are only available for region one, so you might need a region free player if you live in Europe. But whatever you do, don't miss out on this classic.
