DataVideo DAC-200: anyone using this?

I've been researching the various methods of getting my old analog Hi8 tapes into iMovie and I've come down to getting a external converter over using a DV camcorder with pass-through. There seem to be 2 converter in the price range I'm in, the DAC-200 from Datavideo and the ADVC-110 from Canopus. I've read a few negative things about the 110 so I'm leaning towards the DAC-200. A search here doesn't seem to turn up anything on that so I'm wondering if anyone uses it or has heard any good or bad things.

BTW, I assume it would be compatible with intel iMac's and iMovie 6 HD but the Datavideo site doesn't say so. Does anyone know if it will work with this setup?
