What camera do you have? some PL lenses are not meant for film cameras.
You can get LOMO PL lenses, many of my friends thats started out in the rental business started out with a set of LOMO's, if you can add more money you can get a cheap zoom lens like the RED 17-50 for 3.5K or Sigma 18-35 rehoused by GL optics for about the same.
You could also try and find the v1 Sony PL lenses that where made for the F3, they go very cheap.
I like the LOMO's as they have a vintage look, so you even if later on you move to modern looking glass, it's always nice to keep when you want the soft, vintage look with some breathing and flaring.
