I'd agree with the advice to skip the Scorpios; I have a couple and they never get played-think in my next culling they'll get traded to the dealer who will sell them to some unsuspecting soul.
The best value BN re-issues, in my experience and without a doubt, are used Liberty or solid blue label Blue Note re-issues from the 70's. The Liberty's are generally a bit pricier-the solid blue labels can very often be found cheap on E-Bay or perhaps at record dealers with a decent jazz inventory. Liberty's in good condition are going to perhaps run $20-$25; solid blue labels can very often be found for $10-$15 if you're patient and they are outstanding value.
The Japanese King Blue Note re-issues from the 70's and 80's are, generally speaking, truly outstanding as well and can occasionally be picked up for $25-$30 if you're patient. IMO, based on a couple of the Music Matters that I have, the Kings while perhaps not quite as good are almost there and the MM series is very expensive in Canada. If I could grab a mint King for $25-$30 I'd do it in a flash.
