Your best bet is building one, or having one built by one of our members. There are no "good" focusable bluray lasers available. Olike etc sells them but I highly suggest a DIY type build for a bluray. A PHR build set around 120mW will run you about $100 in a high quality host with all high quality components. A GGW(200-250mW) build will run about $160-$180, while a BDR (damn near 1/2w) will cost about $400. All this information is available in the bluray section along with the B/S/T section.
