Question Regarding building Lego Camera Mount

Hello like most I have the Camera that came with the studios software and apart from the little mount thing that you can build with the studio set, has anyone attempted building anything better to do this job?

The reason I ask is my other camera has just given up, and with funds being low (AT-AT release) I think a lot better mount can be made.
One of the main problems with this camera is that there is no controlled zoom, up/down & left and right, I think with this it would make it a more interesting camera. Okay if you could fix the graininess this would be even better, but lets not get our hopes up.
Any info on this would be great, controlled tilt & pan would be good also, size and sturdyness is a factor too.
Let me know what solutions or problems you've have as I plan to have a go at building such a device to see if it's possible, regards Marty

Ps no computer control, all must be manual controls.
