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.

Thanks for the responses, folks.
I'd love to hear from anyone familiar with the Sumiko Pearl.
Anyone?
I have used the ShureM97xe on a Technics DD table and was very impressed. The Sumiko Pearl, not so much. But, if you can handle the extra money the Denon will not dissappoint you, much more coherent sound than the Pearl on my table. Take Johnny53's advice, he has never steered me wrong. Kevin at KAB USA would be the person to speak to about DD vs. belt drive and the issue of motor rumble. Care does need to be taken in isolating the lp from the deck, nothing that a good mat can't handle though.

Thanks for the input on the motor bearings. I had gotten the impression that direct drive is more accurate than belt drive, but recently I've been hearing that the DD can have motor rumble transmitted through the system.
That claim--that DD tables are inherently noisy because the platter is an extension of the motor spindle--has taken on the status of dogma among belt drive purists. I've seen it repeated in Stereophile and proffered by many audio sales people, but have never seen anything to substantiate the claim. In fact, the measurable signal-to-noise specs on the Technics and Denon direct drive turntables rival or exceed the noise specs on all but the most expensive (north of $20K) belt drive turntables.

Back in the '70s and early '80s there were probably some shoddy low cost DD tables that had compressed dynamics and a high noise floor, but even then I doubt that it was the motor. Most of the DD motors were made by the inventor, Matsushita, parent company of Panasonic and Technics, so their noise specs and precision would have been similar. In a cheaper implementation, however, that motor might have been mounted to an inferior plinth, accompanied by an inferior arm.

Probably what got this dogma rolling is that the Linn and AR turntables (and later, the better BDs that followed from SOTA, Michell, etc.) were suspended designs. Belt drive designs lend themselves to suspended designs easily; DDs do not. But it is easy to create your own vibration isolation platform for a DD that absorbs the turntable's extraneous vibrations and isolates the plinth from in-room noise and vibrations.
