A good under $100 tent is a rare thing. I read gobs of reviews and websites, etc. etc. etc. about various tents and ended up just recently getting a Eureka Spitfire from Amazon $89 free shipping. I am actually very impressed with the quality of this thing. I just seam sealed it. My junky scale shows it at 3 pounds, but the scale is not very accurate.

The size may be an issue with it. I am 5'4" and room is not a problem. However, I don't know about a 6'1" person.

Of course, tarptent will be the most "treasured" tent by a lot of folks, but they are a bit over your listed budget.
