1000 bucks on your first muzzleloader, the skys the limit almost. I agree it depends on your needs. For hunting I would go for a 50 cal. If you ever leave your bullets behind by accident 50's are easier to find at country stores then 45s. I have never hunted with a 45 but my brother has no problem killing a deer with his. Knight and Thompson are good brands and a good place to start. There is some custom guns out there if you do a search but I would start simple and work my way up.
