the first question most people would ask is budget? Everyone has a different opinion of high-end. But that being said here are a few suggestions
Opus X, Lost City can be found on a number of sites, even CI, price point for individual cigar is about $30, they offer a nice Lost City sampler, 5 cigars for $150 in a great presentation box
Davidoff, lots here to choose from. Two quick lines I would recommend are the Nicaragua (4 pack for under $80) or the 702 Series for about the same.
Like you mentioned the Don Carlos Edicion de Aniversario by Arturo Fuente is a great choice. Hard to find singles or 5 packs. Mostly sold in boxes at close to $300 for 10. Although like the Opus
X sampler you can get a similar one for the same $150. Another great Don Carlos is the God of Fire, again about $20/stick. There is a nice samplers of 5 for about $115
Another Fuente line is the Arturo Fuente Anejo. the No. 888 is a fine cigar and 5 packs are about $60, also most any cigars from this line is worthy, just might take some digging to find stock
I guess you could go on and on, but one more, how about some of the slightly more rare Ligas like the Velvet Rat, L-40. Much easier to find now a days at about $14 - 16 per stick
