Do you mean the Yamakawa 365Divix? I haven't seen one called AVphile.
Is it a good player...
Yes, it's amazing if you want to use DVI out. The picture I get on my projector from a £140 quid player is nothing short of stunning.
I don't believe there is a source in the UK.
www.computeruniverse.net are in Germany, will answer emails in English, will take credit card orders and deliver to the UK. There service is supposedly excellent. I think with postage it will work out around the £140 mark.
There is another place someone pointed out with cheaper euro postage, but you'd have to search the threads.
There is plenty on this player. Search for Yamakawa or 365Divix in this forum and you'll probably find plenty of chat.
Cheers
