Purchased from ebay - http://cgi.ebay.co.uk/650nm-200mW-laser-module-90-240VAC-OEM-2-2VDC_W0QQitemZ110121797961QQihZ001QQcategoryZ53141QQcmdZViewItem

This is a very good laser and it has a TTL input for scanning. The module works off 240v, i have checked this laser with my meter and it measures 198mw, so preety close to 200mw. If you want to put this laser into a scanner it will need some kind of cooling (heat sink or fan). This red does have a pretty good beam and its very visible.
