Beseler Dual Mode Slide Duplicator/Bowens Illumitrans 3S Slide Copier Which One

Hello All:
I'm interested in doing Digital Camera Scans instead of using my Nikon Cool Scan 5000 ED. I have read about camera scans in peters book and on this forum. I have been looking for a decent priced Beseler Dual Mode Slide Duplicator on Ebay and Craigs List. Recently, I came across a Bowens Illumitrans 3S Slide Copier someone has for sale. Looking at the specs of the unit, It should do everything the Beseler can do, but I do not think it has color filtration. My primary purpose for purchasing either unit is to do digital camera scans of my 35mm slide transparenices for my stock library. I think the Bowens will do up to 6x7 trannies and Beseler will do 4X5. Has anyone had any experience with using the Bowens Illumitrans 3S Slide Copier. I have an opportunity to purchase a Bowens unit for under $200 dollars. I can purchase the camera body adapters and camera lens adapters for the bowens unit when I purchase the main unit. I would appreciate any feed back on this subject. Thanks
