Hermes have got better here. DPD have also improved since my horrendous experience with them a few years ago, when it seemed they'd lost a Warwick Thumb 5. My local Parcelfarce delivery man ("we can lose an elephant and break an anvil") is good - a guitar rack arrived yesterday in an inner box packed in an outer box, which was damaged (not the inner box though), and he took a photo of it in case I needed to make a claim.
I've used UPS in the past without problems, and they do good insurance cover. It appears they may have deteriorated since then.
