Lambchop "Nixon" always sounds great on vinyl. Mos Def "Black on Both Sides", too.
Lots of jazz seems to lend itself to vinyl for some reason... Impulse's heavyweight reissues are universally really good sounding and cheap - £10 from places like Fopp! and Honest Jons.
My personal fave vinyl cut is a 12" of Puutarhassa by Pekka Streng on JazzPuu. It's not a special release, cut at GZ in the Czech Republic, but just a great tune that sounds amazing to my ears.
