The Dunlop Trigger is a great go-to capo when you need something light and inexpensive. It's spring-loaded like the Kyser, but I find that the grip is typically less vise-like than the Kyser, which is better for your tuning, at least out of the box (this does mean, though, that the Dunlop loses a bit of springiness faster than the Kyser).
This capo works well, and is less obtrusive than the Kyser in my opinion. Also, it won't fall off if you accidentally hit it like a Shubb. I've had one for about 5 years and play with it consistently and only recently has the rubber piece started to wear away. I'll get another! It's not as nice as the G7th, but maybe a bit easier to use. My favorite capo of this style.
