Can you still buy this on the net as I can't find it anywhere, trying to decide between this and the Humax PVR-9200T which I can buy in quite a few places.

The Humax 9200 from what I can gather is definitely better but it's also more expensive.

The DHD4000 was discontinued a while so no is the short answer, however if you don't mind second hand then there are a few on eBay.

Thanks for this, I can buy the Humax for £180 on the net so it looks like it's going to be that.
