I clip only occasionally, and that's when I've fallen behind on their nails and need to make bigger cuts. Dremmeling takes longer for sure, but I've never hit a quick because it is so gradual a process.
The 1100 is great because of its ergonomics. You can hold it multiple ways so that you can really get the right angle.
The best thing about a dremmel over the clippers is:
1) they don't pinch (though you do have to acclimatize the pups to the noise and the feeling)
2) if you've got black nails, it is highly unlikely you'll hit the quick because its is a gradual reduction.
The $100 pays for itself in less than a year. Generally I like to do nails every 2 weeks, at worst 3 weeks. If I was paying $9 that would be $234 per year, and even if only monthly, that's still $108.
And I had a Pedicure but gave it up quickly. I found it too cumbersome to use and despite the hair guard, fur still got caught. Now I give the feed a quick hair trim, dremmel, trim again and do a final dremmel, and a final trim. Perfect paws!
With my forever pup, Timber, I was really bad about getting his nails done. He would not let me do it, which meant the groomer had to do it, which meant, no more than every 6-8 weeks. As a result, his nails grew so long that they could NEVER be cut back short enough. I'm sure it hurt him walking on hard surfaces. Never again!
