London - Belgium ParcelForce or Parcelmonkey

I need to ship a large & heavy parcel (26 kg, a side table) from London to Belgium. There is no hurry, I am just looking for the cheapest option. ParcelForce and Parcelmonkey seem to have the cheapest prices, but I am finding some horrid reviews. Of course, mostly people who complain give reviews. I sent the parcel with UPS, but it is near double the price to return it to Belgium... And Ijust checked, UPS has horrible reviews too, haha! So does anyone have experience sending parcels with these two companies? What worries me with Parcelmonkey is that just about everything is on restricted items list (freestanding tables incl) and they do not cover in the event of loss or damage. As the value of my parcel is 920€, I do wish some guarantee. Any advice or reviews welcome!
