I have three Sunpak MS-4000 monolight studio flash units. 2 units are completely working. One unit needs a new flash tube.. but I have a brand new in box flash tube included as well. So you can have 3 working units or keep the third unit and tube as a backups. These are nice reliable units with modeling lights, umbrella mount, 1/2 and 1/4 power settings, and optical slaves built in. These are powerful 400ws flashes, not cheap stuff. I will include 2 long power cables and one short. (they use the same cable as a computer) I have 2 PC sync cables included as well. I am in Sacramento if anyone wants to pick up. $200 plus shipping.
