Personally, I think they are an excellent cigar. Now if you ask me if they are they worth the price, it all depends on the individual.
Each line has a different flavor profile. I happen to like the Blue Line, which I believe is the Professional Line. It is a little more potent and flavorful than the Red line. I have one of the Sun Growns sleeping in my humidor for a special occassion, like when I finally find a job.
I am glad that I was able to afford a couple of them at a rolling event last year, but am no longer able to afford to spend that kind of money on a cigar.
