I have a Andre Bardot Trumpet and I was wondering if anyone knew a price range on how much they are worth?

I live in Ottawa, ON, Canada -- and HAVE AN Andre Bardot trumpet that my son played a few years ago in jr. high. I asked the local dealer where we purchased it what it was worth and he said between $200 and $250 Canadian - $1US = $1.10 CA). Hope this helps.
