Howdy Justme!
Did you try using the search engine for 'tent' in the subject?
I recall several threads within the last 6 months here that had good discussions about the various tents. If this search engine doesn't find them you can try google and include the backpacking.net in the search string. For $300, there are lots to choose from and it is more about specific features that you are wanting.

As for bivies or hammocks, I'm a hammock guy.
The best place to find info on hammocks is over at hammockforums.net. Prepare to spend a lot of time reading.

A lot of it depends on where you plan on doing most of your hiking. If you're above treeline, you'll obviously need a bivy.
