I’ve tried a few different manual ones (my latest pair are the same ones my vet uses, sharper than most store bought, but then you have to be more careful how you clip) plus I have the Pedi-Paws, which is essentially a rotating emery board. It works nice, but I used it on my Yorkie one time and found that if you’re not watching closely you can draw blood with that by grinding too far just like you can with a pair of clippers.
Most of my buns don’t care for the noise it makes, even though I think it’s pretty quiet overall, so… *shrugs*
The maker of the clippers I use now is Miller’s Forge. Here’s a pic:


I can bet it’s easier to see nail quicks on a Flemish than it is on my little Holland lop though! 0_o His nails are SO dark I usually just have the vet do them anyway. It’s worth the $15 bucks for him to hate her instead of me. 
(dang, just realized they didn’t trim him during his dental this week…ugh…means I’ll be doing it this month. yipes!)
