I always fancied a Tarptent Rainbow, but what always got in the way was knowing that I could buy nearly 3 Chinese 'Tarptents' tents for the price of one USA tent. Unfortunately, for me, in money terms, it was no contest! The Chinese model (Targa 1) in my view also has one particular design advantage over the Tarptent, which is the inner half circle door which can be unzipped to store items outside of the actual sleeping area. My Marmot tent has a similar zipped area, which I use all the time, I can keep my walking sticks out of the way but I can also grab them instantly if needed. All of my other stuff which I may need, Uriwell, small bottle of water, etc, can be near to hand and I don't have rummage through my rucksack in the middle of the night to find them.
In the end I became so bamboozled by all that I was reading and I was comparing and contrasting with other makes as well, I decided to buy none at all and just decided to stick with the tents I already have.
