I just spat me dinner out, £188 for 4 brake shoes, from Ford, best bet I would say is either use different calipers with built in handbrake off another ford or have yours relined.
Relining will cost between £8-£9 per shoe + vat(tax), plus postage, so say £65-£70 all in.
The people I have used in the past without any problems whatsoever are

They are more than happy to ship to EU inc Germany, hope this helps.
