Everything is a hit or miss these days. You might refund the same item that might require you to submit a PR, where for many others it won't.

You are doing this using the DNA method?

Sorry for the late reply, yes I am. To answer your question, anything that I think can follow sealed box method is probably the easiest (except Apple).

Think of an item that you can buy as new and buy a similar/same item as parts for cheap on ebay or fb marketplace. You can easily replace those. I've heard home depot is doing very well right now too.
