The Opus X line is a fantastic cigar, and are worth some money. How much depends upon vitola. For me my favorites are the xXx, petite lancero, and lancero. These are all great young or aged. The rest of the opus line really starts to shine after a year or two. I have not tried the angels share opus however.
To touch on something tarheel said the Anejo is an amazing cigar. It is not a opus with a maduro wrapper however. The opus x have a Rosado wrapper, and then there were some very limited runs of Opus maduro made with a special maduro wrapper(prepare to spend $100 plus per cigar here). The Anejo is a different binder/filler with a special Connecticut broadleaf maduro wrapper that is only used on the Anejo. They cost about the same as an opus and are one of my favorite cigars.
