Yup, both those breeds are friendly and good layers. ISAs are red sex links, which are sold under a lot a different names. Golden Comet, Red Star, Cinnamon Queen, Golden Buff, and ISA Brown are all the same breed. Easter Eggers are often sold under the name Americana or Ameraucana. Most hatcheries have both breeds, but they use different names from each other.
These hatcheries sell both:

There are more but those are the ones I know of.
Red Sex Links are very prone to reproductive problems due to the amount of eggs they lay, but that can be avoided with proper care. They must have a feed with 18% protein minimum, and supplemental calcium on the side. Treats like scratch, mealworms or table scraps must not exceed 10% of their diet. That is super important to keeping them healthy. They more treats they eat, the less feed they eat, and they need their balanced feed to stay healthy while producing all those eggs.
