Ball Point Pens
I'm not a pen snob so maybe I'm the wrong person to give advice for pen replacements, but I have heard that getting into pens can get crazy expensive.
Jim's Pick
Cheap pens are great because, well - they're cheap and if you lose them it's no big deal.
I know there's reddit groups and clubs all about pens and I'm not that guy as I don't really have much use for a pen and theres always a pen or two in my Glass Pen Holder so I haven't had to buy a pen in a long time so these would do in a pinch.
The only other writing tools I may need would be some Pencils and maybe Sharpie or two and I am good to go.
