I do have some alternatives such as using another computer, but due to the convenience of hardware wallets, I think I'm just going to buy one.
Imho you should use another computer, if you have that alternative, as cold storage, properly safeguarded and always offline/airgapped, at least until the point you are 100% that HW worth it for you and you are convinced 100% on which one to buy.
HW makes sense if you use bitcoin a lot from outside of your home, and the amounts are big. Else, a cold storage for the big funds and an unsafe wallet on your phone for small (daily?) funds can easily do the job.
Of course, this assumes you know what you're doing, but I expect so.
