That'd be a nice setup! Don't think about the cost if that's all that's stopping you - if you're going to buy it anyway, it'll cost the same in the end - you're just delaying the inevitable! xD
You can buy the Zidoo and use an old laptop and a couple USB drives for storage in the mean time
I didn't know much about the Reavon - I thought it cost about as much as Oppo.. looks like they were a good value
