Best quality "budget" cigar in my opinion is the Glorious Rocky Patel "Edge" It burns for about 40 minutes or so and is oh so tasty! They used to run 2 for 5 bucks but now they are buy one get one for about 8 dollars now at the big smoke shops like smokers outlet/wild bills. May be able to find some deals on them in mail order. I buy those local.
Bahia makes some decent budget cigars. Ive had a few boxes of those.
