You are on the right track try them all but one little tip is keep a diary of what you like and what you don't like. After a while they all start running together in your mind as often you like 1 or 2 of a producer but not all of the line.
Now that said you will quickly fry the budget shopping at the B&M for several stix a week, that is fine when it is several a month but adds up quick for a weekly buy.
The devil is good as is the devils brother Joe: (Especially on Jam Days which are usually Wednesday and/or Friday)

Famous and its Devil Cigar Monster have not been offering a lot of good values on samplers recently.
