Dyson DC41 roller issue

The roller on the bottom of the hoover is missing. Found this post which discribes the problem. Turns out it's cheaper to buy the whole head, then to replace this, as the housing needs replacing and the roller cannot be bought separately.

This is a little pricey. But found this suggestion in the comments:

Much cheaper! Don't need the graphics card straight away. Will upgrade this later!
