Never had an Opus I didn't like. I've got a humi full of about 30+ of them from the smallest to the Forbidden-X.
Not all were pricey, none were cheap, some were gifts, but all are exceptional.
Are they worth the money - only if you like em! They're too spicey or complex for some tastes. Not for the timid or inexperienced palate. They give you a nice buzz though!!
But hey - life's too short to smoke cheap cigars!!
