I thought Becoming Queen was great - definitely better than MAgic Moments. The background music in that is awful but the interviews are OK.
Becoming Queen is a lot more interesting, altho' the bit about Brian May goes on too long I think.
I got it on e-bay but you can now get it at good record shops in Australia for about $14.99 - not bad...
