Good and cheap -- Rena Rama, Maffy Falay, Björn Alke, Tommy Koverhult, Iskra, Förklädd Gud are all filed. Pretty diverse range of music from post-bop to very free.
I think you need to check out the Club Jazz series too, inexpensive and interesting sessions. https://www.discogs.com/label/502546-Club-Jazz
Rosengren is generally awesome... the Improvisationer LP mentioned above is strong, definitely not audiophile but worth checking out. Stockholm Dues is incredible, as are Notes from Underground and Fly Me To The Sun.
Börje Fredriksson has a dedicated thread on here somewhere. He's great, sort of akin to Bill Barron IMO.
Eje Thelin, like Rosengren, has a rich discography that goes from bop to avant-garde.
I tend to go for the freer stuff -- GL Unit, Bengt "Frippe" Nordstrom, Staffan Harde, Göteborgs Musikvartett, Lokomotiv Konkret, Gush -- pretty interesting universe of free music coming out of the country during the 70s and 80s, and not just out of the Don Cherry-adjascent scene (although that is a big part of it).
