Yes, they're all much of a muchness: couple of tubes with some degree of zoom adjustment, a lens between them and a means of holding a mounted slide with a built-in diffuser over it. The beauty of such a thing - when the transparency is clipped in the end - is that shutter speed is immaterial; the whole lot moves together so no blurring. I had to get a t-mount to 42mm (got it originally for my Pentax MX) off eBay so I could fit it to my Canon EOS 5D via a Canon-to-M42 mount, but the mount is easy to change: three grub screws and that's it.

I use my mains-supplied traditionally-ballasted fluorescent tube light-box which is great - as long as the shutter speed stays below 1/50 sec, otherwise there's a heterodyne between the flicker rate of the tube and the shutter speed, consisting of a dark area that travels through the neg. I would use either an electronically-driven tube (works around 46kHz so flicker is immaterial) or an LED, which also has a high flicker.
Or just direct cloudy natural light onto it with mirrors!
