Online dating or Not?

Have any of you tried online dating and was it a 'good' experience or not. ie did you meet your soul mate? I am in my mid 60's and have started to give a lot of thought lately to having a male companion/partner/ again after years of being alone. I was fully occupied with work, familydogs and other commitments as well as content with my life, however, all have left the nest now and I dont seem to meet a lot of males in the things I do. Any ideas?
