Congrats! I'm really jealous!
As for saddles Circle Y is a very nice brand (especially older saddles), same with TexTan. I really liked Billy Cook when I tried one, but I don't know if they make reining saddles as well. I know bunch of people own Corriente and really like it, but personally I haven't seen them used for sale (and new will be over $500, although may be if you and dad are serious about reining and later showing it's worth to look into it).
