I got Campion with Peter Davison on DVD the other day. I found it in a charity shop for £4. It was priced at £4 because it was every episode ever broadcast on 4 DVDs. The condition of the discs are quite good.
Haven't got round to seeing Campion yet, though. It has also got Brian Glover in it, and he was in Attack of the Cybermen. Maurice Colebourne was in AOTC too. He was also in Howard's Way between 1985 & 1989
