After only like 2 years of thinking about it I finally got an HDD recorder (think Tivo).
The biggest reason I didn't get one earlier is they are EXPENSIVE in Japan. Tivo was the first in the states (I think) and their business model was sell you the hardware cheap and make you pay for the service. No one has really done that in Japan. Almost all the various units are not attached to any service. That means instead of like a Tivo which is/was $300˜$400 the Japanese HDD recorders were more like $1000˜$1500!!! This last year they came down to around $600 at the low end but still that was more than I wanted to spend.
