When I went looking for my bicycle, I spent days finding and searching through manufacturer sites. Then I narrowed my search down to 50 different manufacturers and debated back and forth between them before narrowing down to 12, and then finally to the one I bought my bicycle from.
You might start with CCM or Norco as they might have something in that price range. I think Trek's touring bicycle is fairly inexpensive. The new Giant OCR3s are more expensive than that, but you might be able to find one that is a couple years old.
And speaking of which, you might check the Buy and Sell lists of your local cycling association to see what might be for sale.
