Glenncol,
The 3000 seems to be a pretty good doubler with a wide range of inputs but beware of the ones you get from USA & Canada, they're NTSC only. Not sure if the ones you get here in Oz are PAL only or multi-system, though.
If you want to see one in action, I have one that and we live in the same city - contact me if you wish to discuss this.
