I bought it yesterday, £29.99 from hmv. Haven't bought anything from hmv in years, and wasn't sure if they'd have it, but they had one solitary copy hidden away.
It's worth the money - the length of three normal albums I guess. The packaging is nice, and the lyric booklet is very nice, with a very long Stephin interview discussing all of the songs which was a great read.
I somehow missed the last magnetic fields album (so will need to investigate that), but hadn't been that impressed with the few albums before that one. This on is definitely up to 69 Love Songs quality anyhow - lots of good songs and lyrics and varied sounds/music due to his instrumentation usages. Looking forward to listening more and finding my favourite songs and favourite disc number (4 currently).
