FS Mountain Hardwear EV2 bivy tent for tall folks
$350
Bought new in 2017. Used once. Nothing wrong with it. Retail was $700.
This is a good tent. MH hasn't made it in a couple of years which is kind of a shame because it has some unique features. You can find someone else's review here.
The major points differentiating it from other options IMO are:
1) integrated vestibule - this is nice if you are tall (6'+), most other single wall mountaineering tents are not long enough and you end up looking like this.
2) stronger than a typical bivy tent, 3-pole design instead of 2
3) more featured/livable than a typical bivy tent - vents, clear windows, large external pole clips (you can set this up with mitts on)
