Sounds about right; 25 to 30 quid was circa $50 to $60 back then. As much as I've always liked VMS20E, I'd describe switching to that from any Shure ED as a lateral move; slight downgrade even.
I rate the VMS20E as considerably better than the Shure. An upgrade from an M75 to a VMS20 was about the most common cart upgrade I can remember there being at the time.
