$1 - Ditto - No such cigar exists - Anything that resembles a cigar for $1 is manure in a paper wrap
$2 - Maria Mancini Magic Mountain
$3 - 3X3 (recently discovered - a nice cigar) OR Quintero Brevas (Cuban)
$5 - Arturo Fuente Double Chateau Sungrown - IMHO the best cigar for your money
$10 - Rocky Patel Vintage (usually a bit under $10) or Perdomo Estate Seleccion Prestigio
