Yes, they were a bit of rarity in the UK - Tower UK was probably the best UK source of them - but as you say they were very expensive. Quite a few I ended up getting from Tower in the US (nothing like going to the 'horses mouth') e.g the Konitz Motion. A few, like the Lalo Schifrin and Alan Shorter, required a major internet trawl to get hold of.
It eluded me too - but rest assured I won't bid.
