The one done by "monthlyclubs(dot)com" comes to mind because my sister gets me their beer-of-the-month sampler each year for Christmas. I looked into that one a while back, and find the cigars are nothing that cannot be found locally at a much better price than the club offers. There are many awesome samplers on cigarbid that can often be had for little more than a couple of dollars per cigar, and on better selections than most of the club deals.
One thing to consider, whatever you end up with. From personal lessons learned: Don't judge ANY of the cigars in the samplers based on one stick. Differences in humidity, aging, past and present storage can all give a stick different draws and tastes. So, if you can, look for samplers that have at least two of each cigar. Smoke one as soon as it has stabilized in your humidor. Then come back in 3-4 months and smoke the other one! I've been surprised so many times with the second stick, that I hardly post reviews of the first stick I smoke in a line.
Oh yeah...... If you haven't already heard of Cigarbid, I'm sorry to be the one to kick you down that terribly slippery slope!!!
