I use 2 First-Up 10 ft x 10 ft tents from Wal-Mart as my display tents. They're less than $90 and my two have been very reliable. You can also get side curtains for around $40 per tent that you can put up on the sides of the tent, zip closed, and your merchandise is somewhat secure for the night. Well, it's out of sight for the night - ripstop curtains and zippers won't stop determined thieves. The curtains do a good job of stopping wind and rain and the tent top is largely rainproof. There have been reports of seams leaking, but I've not had that problem.
