Same with everything I own, memories fade unless I write them down.

Man, I gotta say I don't totally agree with the idea that prompt packs are a ripoff just cause some overlap with free stuff. I've bought two packs for like $15 each and yeah, maybe a handful were ones I'd seen before, but the other ones gave me angles I never would've thought of on my own, and that alone was worth it to me. Half the value is the sorting and the order they put them in, not just the raw prompt itself. That said I do keep my own running doc of favorites, so I feel you on not wanting to pay twice for the same words.

I did the exact same dumb thing but in reverse, bought a Rolleicord at a flea market in Stockton and then spent a month complaining that the crank advance felt cheap compared to my buddy's Yashica. Turns out I was just bad at focusing and blamed the gear. The dim screen thing is real though, my Rolleicord glass is way easier to nail focus on at f/3.5 and up close, so if your soft shots are all wide open and near, that's probably you fighting the screen and not the lens. For 70 bucks a new screen is cheaper than selling at a loss and re-buying, so I would try the screen first before you go chasing another camera.
