Having only had the Varese recording on an illicit cassette copy from a friend years ago, I jumped at the chance of the expanded version. Sure, it was a lot of money (and even worse when you factor in the ludicrous amount of postage to the UK), but I've not regretted it at all.
I'm not quite as much a completist as many people - I love Far and Away's score, for example, but have no desire to splash out on the recent definitive version when the original CD is so good - so if one of the new releases is good enough for me to buy, that puts it in a minority.
