I am glad you asked, I have quite a few suggestions as I too like to keep this hobby as economical as possible while not smoking dog turds.
Here's a quick list...
Arturo Fuente Cuban Corona's in both natural and maduro
Arturo Fuente 858 Maduro's or Candela's if you friend likes a mild to medium cigar
Padron #5000 or any cigar really from the standard Padron line
La Aroma de Cuba Corona's or Belicoso's
