Thank you for all your work on this John (et al)! Question: I’ve seen a couple consignment MSR Guardians at my local outdoors shop. Would you be comfortable depending on a used Guardian if there’s no visible damage? Or would you be more confident in using a new but less expensive option? I’d like to get the Guardian eventually but it’s not in the budget at the moment 😀 I guess I could test the water to see if it works, but that would cost more money and I wouldn’t be confident in my results. Thanks!
