Sweet guys thanks for the tips... DigitalNow fairly cheap too! $169 for Twin Tuner PCI, thats nice
Does USB work well? I am more inclined to stick to PCI I think as external peripherls look messy

I only require a Twin anyway so replacing my current HD Card and using a Twin would work fine.
Not sure how MCE recognizes the two tuners and how it works out which to record on, but I'll work it out when I get it!
Thanks again peoples.
