Lots of comments here, plenty of information for you. I'll add to the pile that I started playing with my buddies stock ender 3, fought it often, lots of tweaking and configuring.
Then I got my own ender 3v2, and fought it less, but still needs tinkering. Usually though I can fire it up and print small stuff without touching it. I print infrequently these days, so the procedure usually involves wiping the dust off the bed first. But it works well enough for my needs.
I tend to get into hobbies for awhile and then back off, so I'm glad I didn't spend more. And really, while $300 is a lot of money in many ways, in some ways it's not so much. I'm glad I have a printer, it is occasionally highly useful. But I'm glad I don't have a $600-1000 printer. Personally 🤷♂️ but that's just me.
