I was in exactly the same position waddler. I was set on a manual but tested a DSG just out of interest. I really couldn't decide for ages and had a few debates on here. Most people do tend to favour the DSG system on here and as an automatic it is awesome. At the end of the day, this is my only car (unlike some rather lucky Docs out there...!) and I couldn't live with an auto 24/7, so I'm still getting the manual.
Like Doc says both transmission are excellant and do what their supposed to brilliantly, you just need to decide if YOU are a manual or auto driver. Maybe think about the type of driving you do too, I'd be in an auto if I did a lot of city driving or a long commute, but I don't and I enjoy using my left foot!
