Sent you a PM, but just in case you're busy:
Near downtown is Cigars on 6th. They are the big Tatuaje dealer as well as Ashton, Fuente and Padron.
If you're in the south side of town near Centennial/DTC, I'd recommend Stanley Pappas. They have a decent sized selection as well as several sizes of Opus. The staff is very friendly and their lounge is a Diamond Crown lounge with several good areas to relax.
In Aurora I'd recommend the Smoker Friendly on Parker/Havana. They have 2 walk-in humidors and a dedicated lounge across the parking lot.
Regards,
Randy
