best cartridge under $500


I purchased a VPI HW19 Mk3 w/ sme 3009 series 2. I would like to stick with a $5-700 price range. I have lot of used records and 180 gram ones, also "rough" records that have some scratches. Is there any particular cart or stylus type would you recommend?

Audiofeil, how did you like the AT-150MLX verse some of the vintage you have tried ? Nice, current, easy to buy, but how does it compare do you think ?

Any info appreciated.
