Do it yourself - buy a small soldering iron, try out some practice solder joints and then do the repair. Far cheaper and more fun.
I recently fixed a headset for someone - it was not a DC (cannot remember the brand) - they wanted $100 to fix it. Brought it home - took a few minutes to take it apart and found the wire from the volume pot had broken. Took a few more minutes to solder it back and it was as good as new. Zero cost for parts
For the UK another place to consider buying from is RS components - it used not to be the case but I think they now do sell to the general public.
