If you're looking especially for a single skinned tent, then it might well be light but it would have some possible disadvantages. No protection from midgies and assorted carnivorous beasties, no protection from wind, and from the examples quoted, rather expensive. I enjoyed reading a few posts from Alan de Enfield regarding a tent he bought off Ebay and it might well suit your needs.
Made in China it has two skins, with the inner only having mesh from about halfway up, very roomy and quite light too. Another advantage is that it would only cost about a quarter of the American tents mentioned. It might be well worth checking Alan's posts as they have a very detailed description of the tent and several photos.
It strikes me that single skinned, or double with all mesh inners may be fine for mostly hot/warm conditions; but Tarptent started making a version of their very successful tent (Scarp) with a mostly solid inner and a lower outer for the European (especially British) market, after repeated requestes from British campers for those mods. I've got a double rainbow that had mesh sides and ends sewn onto the outer (in effect, a single skin with insect protection) and what I found is that the ends let in driven rain and the tent was "breezy" to say the least.
Now, after a lot of mods and needle [censored] in thumbs and fingers, I've got something between a Single and a Double skinned tent. Think I'll casll it a Dingle!
