Yes, I bought this in the end, and I have to say, it was well worth the expense. Haven't got through it all yet, but especially love the 'Monitor' stuff, and the raw version of 'Out Out Out' on the third LP. The first LP of 'early experiments' is interesting, but hardly enthralling, and probably the weakest one. However, in fairness, it's not presented as anything other than 'rough sketches'.
