A friend of mine has satellite freeview and is now looking at getting a recorder. Which model would you recommend at a good price?

Preferences:

1) Can record two channels at once
2) As a plus, be able to watch a third channel while other two are recording
3) Internal Hard Drive - the bigger the better

If the machine doesn't have preference 2, she still has her old satellite freeview box for viewing. In the case of having two machines, do we use a satellite cable splitter or is it possible to daisy chain the signal like you can with UHF?
