DIY Concord Kettle

Has anyone tried to use one of these CONCORD DIY Home Brew Stainless Steel Kettle
. Thinking of a way to spend some of that hard earned tax return, and was curious if for the savings on the SS Kettle and drilling two holes is worth the effort to drill the holes. Going to do BIAB most likely 3 gallons, maybe the occasional 5 gallon, so was looking at the 60qt which comes out to $163.99 with shipping. I have never drilled thru SS and not sure how difficult it would be, it looks like the kit comes with the drill bit so that’s a plus.

edit: Also going with that size put what BTU burner would you guys recommend?
