My current go-to tent is the one person Fly Creek Platinum 1 - from the prices you give, I assume you are looking at solo tents, also. I've been very pleased with the Fly Creek.

However, if you'd like to save some money or if you're worried about space more than weight, take a look at the Big Agnes Seedhouse series. The Seedhouse is a slightly heavier (some might say that means more durable) clone of the Fly Creek. The Seedhouse 2 is the same price as the Fly Creek HV 1, but has more space and weighs a pound more. The Seedhouse 1 is $80 cheaper than the Fly Creek 1, and weighs half a pound more.
