Are questions with the following structure on-topic?
I have X piece of gear that is now worn out. Unfortunately the manufacturer no longer makes X or has drastically changed X into something I don't want. Can you help me find something that is as close as possible to X? The features I especially liked about the original X are A, B, and C. D is an optional nice to have.
I have a question that related to a daypack that I own. North Face has radically changed the design of the Big Shot backpack, it was a simple three pocket design before, and I'm not interested in the new version. My worry is this is shopping related (generally off-topic), but not price specific which makes it potentially on-topic. Of course history has shown that these answers will go out of date since that is the root of the problem. This matches well with the reason why shopping advice is off-topic.
Furthermore, the classic scenario where this is a problem is with shoes, and the consensus seems to be if you find shoes you really like then buy multiple pairs because you'll never find them again. So I suspect that this format of question should be off-topic, even though I'd find it helpful at the moment. What do you think?
