Online unis?!?

Was wondering if anyone knew of any good online universities to apply too/register for. I live in UK but i am aware that there may be some international unis that do do online undergraduate courses so if anyone knew any unis (other than open uni) that i could potentially apply too thatd be great.
If not, does anyone know if the ou is a good uni as idk anyone who has done it

The OU has been great for me so far (in my 2nd stage modules right now). I can't recommend it enough.

What course do you study?
I really am considering OU so i hope the staff are helpful despite it being online

I study physics. The staff are very lovely (at least the one's I have had so far). Most of them will reply to emails in a reasonable time - if not there is often people availible on the forums to help explain things.
