Any particular system you're interested in ?
Otherwise, try calling Flight Safety at Le Bourget airport in France. Maybe you can buy a Dash 8 training manual from them. They provide an excellent manual (in color) for the Dash 8. You can also order type specific manuals (e.g. DHC 8-102,DHC 8-311 or DHC 8-314) directly from Bombardier in Canada.
Five years ago this was the number to call or fax to order a manual: 416-375-3830 (Canada). Haven't used it since.
