Most of the major brands have repair programs. Big Agnes for example has a list online of what they charge to replace a zipper or tent pole. In your position, I personally would look up top rated 6 person tents or maybe go with two 2/3 person tents. Read through some articles and narrow down the list based on budget and the repair policy listed on the manufacturer website.

Maybe something also to consider would be ease of set up. I had a Coleman at one point that was super easy to fold out. No poles in sleeves or anything like that. I also had one that required guy lines to set up that was a huge PITA. If you got kids running around, an easier set up would be convenient.

I started off school with an HP laptop and switched to a cheap ASUS Chromebook after the HP started having issues. I did everything through Google's version of Microsoft office. The Chromebook was like $120 and I have never had an issue with it, even 8 years later.
