like other have suggested to me and i will be moving toward next summer. Both would be the perfect overkill. The oasis will be great in the winter when the heat is on, which removes alot of RH from the air. But if the power goes out they stop working and dont come right back on when it comes back. You must open it up and turn it back on. What if you on vacation or something at that time? Your collection could get ruined.
Now with the beads you wont have that worry but you may need the oasis in the dry winter months. Also the oasis has a built in fan which help keep air moving around inside the humidor. Sure this route might be alittle expensive but it will be highly effective and fail-safe should the power go out.
