I wasn't fearful of doing the crack repair myself, was more wanting to keep the return option available in the off chance it's not something repairable. That being said, I'm probably being overly fussy. Chances are that at least Steve can fix it, and it will probably be worth keeping.
Also, I doubt that they opened it before selling it anyway. There's no way they'd have to know that I attempted a repair and that it wasn't repaired in the past.
I'll do that simple repair and report back.
