Alpine SXE-1025S. Built to be quite shallow so, as I found out, very easy to install into Nova MK2 dash.
You can give them some serious pasty and they'll deal with it too.
Motorworld have them at a great price too.

I can testify that these took literally 2 mins to fit (once i had dial surround off). I've tried Kenwoods before, and were biatch to fit, these were great.
