I think that your money would be better spent on a decent base layer, which you don't need to spend a fortune on. The wiggle.co.uk own brand (dhb) is pretty good.
I usually run in a base layer and short sleeve top in the winter. If it's really cold I add a lightweight jacket that can be taken off when I get warmed up.
The problem with a fleece is that it traps the sweat inside, which gets uncomfortable.
