Cigars - Suggestions?

I'm heading to Nicaragua soon and would like to buy cigars for my family members as souvenirs. I know they prefer to a milder cigar. I know nothing about cigars, so wanted to elicit some opinions on which cigars I should buy for them. I'd like to get something special that may be hard to find in Canada where I'm from.

Also, where is the best place to buy cigars there? I will be in Managua, Ometepe, SJDS, and the Corn Islands during my stay, so won't be going to Esteli where I know the factories are. The easiest thing for me would be to buy them at the airport in Managua. Is it significantly more expensive to buy at the airport vs. in Managua?

Thank you!
