Train Horns

[Lonestar10]

I have a lonestar is damn near looks like a train but sounds like a rediculous volvo when i hit the button.. so who has some experience with air horns to give me a good recommendation in the 100-200 american dollery doos range for a set as close to actual train sounding as possible. tired of kids giving me the international toot your horn arm gesture and sounding like a stuck pig instead of making em crap their pants.

Thanks for any advice!
