What is 'cheap'? That Aqua Terra is cheaper than any watch I have purchased int he last 2 years, so to me it is cheap! Also, the AT doesn't look anything like the Tags, and that Tags are chronos and the AT is not. So what do you consider important? I think if you want some responses you need to flesh out your question a bit more. Nonetheless, look for Seiko 5s. They are definitely cheap compared to the watches in your post.
That seiko is nice. Beautiful dial. I haven’t looked into the price of them yet but I wouldn’t mind getting one.
For under $300-Seiko. I do like the Junghan's chrono's- very sleek but thrice your budget for a mechanical movement.
