You have quite a varied selection at
http://int.barrabes.com/tents - tents available in the medium to higher price range, but the quality matches.
I found a tent locally, namely Salewa Denali II. It weighs just under three kilos, and both of us with the dragon can fit in it very comfortably. There's always room for at least one backpack inside, the other can go in front of one of the two entrances.
I prefer tents with two entrances because the draft cools and ventilates it in the heat; you can use one entrance as storage; in bad weather you can heat something there without issue, although the tent itself is tall enough to do that comfortably inside.
I mentioned above that you can easily fit one backpack inside, but with sleeping pads; without them there's room for a third person.
I use sleeping pads because they are comfortable, because you can't always gather softer materials under the sleeping spot in nature, and because the pad insulates in colder months. But you have to account for comfort taking space, so tent, pads, and sleeping bags make up two-thirds of the backpack contents.
