Got the cable off ebay, mate brought his over last night and we set it up on my HD Projector, sorted the settings and WOW it looked SO much better than on my Sony 28" CRT. Was very impressed, before I hadnt been and contemplated selling the xbox.
However here in the UK the HDD's are not available anywhere, those on ebay are going for £30 over the retail price! Wonder if they will bring out bigger ones also, 20gb is small in todays world, that wont even be one full next gen DVD (HD/Blue-Ray).
I have a car so travellings not an issue, but I dont think they do a cheap bus to the US, I'll double check though
