if you can, go to a thrift store/yard sale of such, and just get any digital camera, 80% of the time it'll work fine and be worth it, plus they shouldn't be too hard to fine.
BUT, i would recommend a Polaroid iD1440, it's not an expensive camera, if you find it for over 100, your being scammed, you could easily find it for cheaper. it's a digital camcorder which takes good photos and videos, all while having that nice 2000s feel to them. It's got a little flip out feature to it, I'm not sure how to explain it but it's fun and useful. if you download a manual for the cam online i think you'll get what i mean.
If you'd like more of that 2000s feel, Vivitar vivicam, i have S124 and it works great, although runs on three expensive triple A batteries lmao, the ones from the dollar store don't work on this thing for some reason. . . Overall shouldn't be too expensive at all. it's got a nostalgic vibe to the photos, it's a cute little thing and easy to navigate. . .
I would mostly recommend the polaroid i mentioned earlier, but that is out of my personal prefernece, do more research and see whats the best and most affordable option for you.
also i like your pfp.
