hello ramsoh

For graphics the 650,s are not ideal because of the fat beam. Also they hardly fit on your mirrors so you loose quite alot of power. If you want to build a profesional system start with a green. Ad red later and go for the 640nm that Marc sells or dave from lasershowparts If your interested i have a 500mw viasho green for sale. Also a good quality scanset and dichromounts. To make it easy the best way is to buy te board from MCcarrot. This way its peace of cake to wire your projector and the board has most safetyfeatures you need when doing a show.
