I have a buddy that uses Seery they work well.
I have so many it's hard to tell on any given day which i'll use. The bulk of my "Active" calls are primos (Randy Anderson series). For your context you will want to be able to do both howling and various prey distress sounds . The primos lil' dog can do both of these chores and is decently easy to use (considering it is an open reed).
But as a beginner I would also get at least one or two closed reed calls, if you can breath you can call with these. Match the pitch to the expected prey (cotton tails or jacks) and get one that is loud and one that is soft. I have used variable pitch calls before but they are usually set and left so I am not sure they are worth it.
