Sears really rocks on his own sides! I bought four compilations with minimal overlap over the years and really enjoy them. His one Prestige LP is totally different, played with a lot of feeling and elegance. An excellent musician.
That said, I have all the Ellington Mosaic boxes, the big RCA box, the French 1950's LP box, and many single CDs - only a few other things I would buy if I find them at decent prices.
