Joe, I have a Bob Jackson Audax Club. Got the frame (£380) from BJ and bought a Veloce 2008 groupset and Ambrosio Excellence/Chorus wheels and put together the other bits as I went along. Whole shebang for about £900. Don't think you can can far wrong with this frame and it's cheaper that the others you mention. As a winter trainer I think you'll be fine in 631.
