Hi, I've nearly completed a BA (Hons) Literature with the Open University. It's a part-time 'distance learning' degree, although we have monthly face-to-face tutorials and online tutorials and forums and the tutor is only ever a phone call away.
I've loved every minute of my degree, have been doing it part-time whilst working, which means I'll graduate with no debt, and am on target for a 2:1. Not bad when I've got a full-time job and a partner, house and writing career (including on here) as well. My degree will also have cost me less than one year at a full-time 'traditional' university.
A lot of 'brick universities' disparage the Open University, but a LOT of employers love employees who have educated themselves this way. It proves they can multi-task, for a start, and aren't afraid of hard work and commitment to continue such a busy life for so long - because my degree is part-time, it takes six years instead of three. So employers see the amount of dedication that goes into it and are impressed.
I also wouldn't class the OU as 'mass-marketed', so perhaps I'm not the best person to answer your question, but I am passionate about my University and about people appreciating that we work just as hard, if not harder, as those attending 'brick universities'.
