Jwglista's advice is good but I have to disagree with the statement "Beware of mono recordings". I like; make that love mono recordings. Vintage 1954-1969 mono recordings are among the best sounding LPs I own. To repeat; certain labels are well known for better sonics.
Many mono LPs were played (and damaged) with older stereo cartridges and much of the noise will go away if you use a dedicated mono cartridge. If your not hunting for certain records, i.e. original mono Blue Notes, the mono pressings are often cheaper and sound better. In my experience, early stereo recordings are of variable quality. You limit yourself from enjoying a number of great performances, especially if you are a jazz or classical afficianado.
Good hunting!
