It's much slower than a Betterlight - if you can imagine that
It uses older software on OS9, I think. Might be a little dicey to work with outdoors, but for still-life in the studio, if you have a lot of light, it's still very usable. You might need to stock up on G4 towers and SCSI cables, though! Typical value would be around $700. The good news is that Betterlight still supports it, and Mike is very responsive.
Cheers,
