I always use a company called Parcel Monkey and find them far cheaper than anyone else, I sold my Miltek to a guy in Aberdeen and it cost around £30 from memory from Cambridgeshire, to be fair it was boxed well in rather a large box I got from work, not sure anyone would take it unboxed. Have also sent a motorbike engine to Germany with them. Excellent service.
Just used them to send my son a pair of trainers to Dubai also at a cost of £38 when everyone else wanted around £70, arrived in 4 days.
Hope that helps
