I was with Amazon till they transferred to Lovefilm. I told them not to transfer my account, but they did, and I had about a month with Lovefilm before I managed to cancel.
For a time I received unmarked DVRAB that were obviously Amazon stock and Lovefilm branded DVRAB. The percentage of faulty DVRAB was much higher with the Lovefilm ones, which makes me reluctant to subscribe to their service.
I'm looking at Cinema Paradiso at the mo, as I like the fact they stock a lot of foreign films.
I do agree that it's a pity the choice is so narrow now Lovefilm has gobbled up most of their rivals.
