I don't know when you need the tent, but there are certain times of year when EVERYONE has sales on tents & camping gear. If you can wait, I'd get it on sale. The only sales that come to mind are for Father's day, but I know at times I'd pull the flyers out of the paper & all the outdoor stuff was on sale.
We have a 4 room from Target. It's very large & T shaped. We had room for an unzipped sleeping bag in one "room," & all of our gear in another. The 2 main rooms were open (we took down the curtain), allowing for a queen bed plus a big chunk of floor space. It was really too large for us (me, DH, DS 2). We set it up in the living room before we left, but decided all the space would be fun.
Target sells 2 brands - Eddie Bauer & the other one. our tent is the other one (sorry I can't remember the name!) It's not great quality and one of the zippers broke. The Eddie Bauer ones seem better. I would buy one & set it up (inside) to see how you like it.
We own 3 tents, this one, a cheap 2 man dome, and a 4 person Kelty. When you assemble them all at once, the quality of the Kelty is evident. But for 2-3 times the price, it may not be worth it. I know that tent will last for a very long time. It's got great ventilation, nice rain fly, etc. We can't use it right now, but it's a keeper.
I don't know if this is helping! If you want to keep this tent forever & have money to burn, check out higher end tents from a hiking store. Otherwise, look at places like sears & Target, but beware of really cheap tents
Oh, and for care. It will tell you, but you can also consider sealing the seams. The most important thing is never to store a wet tent! And it's a good idea to put a tarp underneath the tent to protect the floor, although they make the bottoms stronger now, so you don't really need to. Make sure it doesn't stick out from underneath, because if it rains, the water will be channeled under your tent.
Sorry this is so long!
