What size are you looking for?
What size and wt of tent are you looking for? For example, I fly in an RV-6 and am very weight conscious and need room for two. I also wanted something that will stand up to high winds. In my case I have a 3 man light wt backpacking tent that has aluminum poles (strongest). It weights only 6.5 lbs and with full (to the ground) rain fly it holds up to strong winds and heavy rains with no bending over or flooding. REI is a good vendor for this type of tent as is many other backpacking camping special stores. Look for a 3 season tent, you are not planning a mountain expedition. With smart shopping you can get a good tent for $150 to $200.
From my personal 30+ year OSH experience, if you go with a cheap tent from a big box store, with fiberglass poles and a rain fly that only comes down 1/2 way, it will do you well for 5 out of 6 years at OSH but when that big storm comes plan to take all your clothing and bedding to a local laundry to dry them all out.
Good luck on your search.
