A decent tent will run you at least $200, with some large models reaching four figure prices. OneTigris, Naturehike, POMOLY, and FireHiking are good starter/cheap brands. Buying used here carries the risk that the tent will have ashburn holes, as most hot tents inevitably get regardless of how good your spark arrestor is.
