Best cartridge under $100 - vintage Akai TT

I recently acquired a vintage Akai AP-Q80 direct drive TT, fully auto, with a "S" tonearm, standard mount. (My Beogram 4002 crapped out.) It has an ADC Ser-III cart and it just doesn't sound very good. Stylus cantilever looks corroded.
I'm running it into a Proton 1100 pre-amp with nice sounding phono stage for MM or MC.
Cartridges I'm considering:
• Sumiko Pearl
• AT-440MLa
• Ortofon OM-5E, OM-10, OM-20, Red
• Denon DL110 (a little outside my budget)
• Grado - Pick a color

I'll be playing a mix of classical chamber and symphony (CBS Masterworks, digitally remastered), classical guitar. old rock, blues, Dizzy and Miles. (Some are noisy LPs.)

My budget is really at $100, but if I can get something that will do the job at $60... after years as a carpenter, my hearing is not as refined as it used to be. I'm a bit sensitive to upper register harshness.

Any help??
Thanks in advance.
