Loupes will work fine, I think min is 60x
There's also little hand held scopes with like a 60x-100x range
The issue with these are small viewing area and getting to the buds sometimes, I don't bend as well these days, lol.
The digitals are nice because you can usually get good pics etc with them. Keep in mind they are corded, so getting it to the plants can be an issue, and if you don't have a tripod or the scopes won't mount holding it still can be a bitch. Many do come with a little stand and exam tray but getting it where you want can be difficult.
they'll all work fine.
