I had a new installation recently when I moved house, and wanted audio out from the box, so when I was offered a 4000 I asked them nicely, they had a rummage in their van and I got a 2000 instead. Works well enough for broadband, and joes the audio out job.
They'll usually have either a 2000 or a 4000 in the van, just be nice and offer a cup of tea etc
