I actually have Betty Boo but I bought it when it came out, and it's in a box I keep for 'oddities'.
I wouldn't buy it now as I only collect US originals, not really a hangup, I can play the unissued stuff any time I want as most of them are on CD or Youtube.
A lot of the comments so far are from people who want them to DJ with.
It seems that everyone is a DJ nowadays.
I think the records Ady has discovered and released are fantastic. The RCA/Pied Piper stuff in particular.
I buy many of the Kent Cds just not the vinyl.
