Suggestions please.

Intended use: browning, caramelizing, putting some char on the occasional dessert or shrimp.

I have an old Bed Bath Beyond one that runs on butane. Looks like this The striker is shot and doesn’t spark to ignite the gas. I like that it can be refilled using over the counter butane as opposed to some models where you have to order a specific canister that screws into the torch head.
I don’t need anything as complicated as the Searzall that attaches to a contractor-sized canister of gas.
Thanks
