I've NEVER forgiven NJD for their "Events Projector" which sounds similar to the Constellation 3E.... I've sold the stupid thing now after getting NO HELP and all the usual avoidance tactics ("he's still in a meeting")
The NJD Events projector had a gobo wheel on-board with about 12 gobo's on it (or was it 8?)...with "Congratulations", "Happy Birthday", "Merry Christmas", "Happy New year" etc... AND (heres the good bit) AND the "promise" of "themed event wheels"...eg: A whole gobo wheel of JUST wedding gobos, or JUST Christmas Gobos...
These themed wheels sounded really great...especially as the projector had a remote control which allowed you to set each gobo to be displayed (each gobo was displayed in 20 places via mirrors) for so many seconds, then the next gobo appeared. Doesnt this sound good so far?....for example, with a Christmas themed wheel in, you could have 20 seconds of "Happy Christmas" gobo's all over the walls and floors bouncing to the beat, automatically changing to 20 seconds of "Snow flakes", 20 seconds of "Christmas trees", 20 seconds of "Santa's", etc etc etc marvelous...
NOT... NJD never released the themed gobo wheels... so I was stuck with just the original "multi-event" wheel....
So, at a wedding you'd get 20 seconds of "Congratulations", then 20 seconds of "Merry Christmas"

, 20 seconds of "Happy Birthday"

, followed by 20 seconds of "Happy New Year"

and so on...
NJD did give me the contact details of a company that would make up my own themed gobo wheels suitable for the projector...but "one offs" would have cost about £140 each wheel... the whole projector only cost £229.
If it wasn't for the fact that I like my NJD LV4000 light controller and Dimmer pack, I'd really let fly at 'em...
