I am currently looking for recommendations for cigars to fill up my humidor, and also looking to see what the best humidification system there is right now.
The recommendations will come in bucket-loads. There are also numerous threads you can browse that will show off daily smokes, recent purchases and the like.
As for my suggestions, I offer you to try a few from these various brands:
Tatuaje - Reserva lines are wonderful. However, most of their regular lines are also enjoyable. The cheaper "Tattoo" option is a decent smoke at the price as well.
Illusione - The Epernay series is a little lighter, while the standard Illusione lines are good. Give the Rothchildes a try, it's a favorite for many around here. Another great "cheaper" option that can be enjoyed.
Drew Estate - The view on these can be polarized around here. Some like them, some don't..I enjoy the Nica Rustica and Herrera Esteli blends and always offer those up as suggestions to people interested in trying new cigars. ACID's are good if you like infused, though I don't go that path. Tabak Especial or the Java line if you're a fan of coffee. Many are fans of Undercrowns and the Liga series as well.
All three brands, regardless of personal opinions, offer quality products at a not-too-unreasonable price. There are, of course, countless others but those are fairly easy to find and won't generally break the bank for making yourself some samplers.
As for humidification systems...You'll be split here mostly between Heartfelt beads and Boveda packs. I personally use Boveda. They are about as easy as you can get. If your humidor holds well and has no problems, I'd recommend going the 62% packs - 65% if you want to be cautious. Most here prefer the 61-65% storage range, as the cigars smoke cleaner and the taste is better. Not to mention you'll run into far fewer burn problems than storing at the "recommended" 70%.
