My favorite herbal liquor is Becharovka, it's slightly less sweet then Jagermeistre, but still really smooth and tasty, it goes really well with soda or Tonic or just as is (personally I think it's better in room tempreture but a lot of people like it frozen). I don't know about USA prices, but in Israel it was less then half price then Jagermeister.
Give it a shot (no pun intended...) it's really good!
