I have a handful of these now (Music Matters, Analogue Productions, Speakers Corner) and I'm pretty hooked. I especially love the 45s - Hank Mobley's "Soul Station," Horace Parlan's "Us 3," Art Tatum Group Masterpieces v. 8, Blakey's "Night in Tunisia." Art Blakey's drum solo at the end of "This I Dig of You" on Mobley's Soul Station made me realize once again why I'm truly fortunate to be able to listen to this particular music, this particular way.
The Sarah Vaughan/Clifford Brown reissue on Speakers Corner is excellent, too. It's my ol' favorite & I love it all the more listening to it on vinyl.
Dropping $50 a piece on reissue 45s seemed painful at the moment, but after listening to them, I have no regrets. Original pressings of some of these records would be exponentially more expensive anyway.
Any other recommendations?
