Why am I always the contrary one?
OK, some years ago we splurged on an expensive REI tent. We spent almost $300 on it in the 1980's. Even with careful care, it was toast after about 7 years. The tent fabric tore and several of the tent-poles broke even though we had always been careful with them. I was quite bummed so, when I went to buy my next tent, I bought a $35 tent at Sears by Hillary. I have had it for 7 years now and I have abused the heck out of it because it was so inexpensive that I haven't worried about taking care of it. It's still in almost brand-new shape!
And we've actually used the cheap tent a lot more than we used the REI tent because, at that time, we did most of our camping in our truck camper and then in a trailer. We don't own those anymore and are now strictly tent-campers.
Here's a contrast in how we cared for each of these tents:
* The REI tent was never put away wet. If we had to roll it up wet, we'd take it out of the bag and hang it in the garage until it was dry before putting it back in its bag. The Hillary has been put away soaking wet and not a bit of mold, mildew, or other degradation has occurred.
* With the REI tent, we were quite careful about using it. We never went inside with shoes on. I always swept it out carefully, etc. We've gone in-and-out with shoes on with the Hillary tent, been far less careful about sweeping it out and have even rolled it up with leaves and other debris inside if we've been in a hurry. No problems.
* I invested in the footprint ground cover for the REI tent and used it religiously. I suppose it helped. It sure didn't hurt. But I have rarely used any kind of ground cover at all with the Hillary tent. I usually just plop it on the ground. It has never torn or had any problems without using extra ground protection. The only time I've bothered with additional ground cover is if I'm forced to place the tent on a particularly rocky area so I do it more to protect myself from the sharp rocks than the tent from being damaged.
My REI and Hillary tents have virtually the same features. Both have interior storage pockets, a nice raincover, stay dry inside even in lots of rain (and living on the coast of Washington state, we do have done our share of camping in the rain!), set-up/take-down quickly, don't require ground stakes unless you want to use them because of intense winds, have good ventilation/door systems, and are virtually the same size. They pack down to roughly equal size as well (backpacking size). The Hillary tent weighs about 1# more. This might be a factor on a long backpacking trip but wouldn't matter a bit if you're car camping.
From now on, if this Hillary ever needs replacement, I'll either go for the inexpensive Hillary brand or some other cheaper option. I see no advantage to paying more for an expensive tent.
Caveat: If you're going to be doing mountaineering, winter camping, or camping where intense wind sheers might be an issue, then a more expensive tent might be a worthy investment.
