Not cigarillos, but in the spirit of quick smokes, I'll toss out Nasty Fritas and Dante.

Nasty Fritas is a pyramid shape that gives you the full cigar experience at light up.. Its stupid strong for the size of little cigar.

The Dante comes in a mini size thats meaty and reminds me of Drambuie.

iirc, both can be had in the $4 range?
