I'm looking to replace my 605b's laser, specifically looking to buy one from aliuy.com. At the site he says his lasers are only to be replaced with "SOH-D12 or SOH-D16 lasers". My current laser is a SOH-DR16S, so does that place it under a "SOH-D16" laser? I tried contacting the people running the site and still have no response, so I thought I'd come here and try it out.
