Icorem,
There are three things you should consider. One is the effective mass of the FR24 and compatibility with a particular cart. The second is the phono stage especially resistance and capacitance load. Third is overall type sound desired.
I'm not familiar with the FR24, but some of the FR arms are high mass and the 24 looks similar to the 64 which is heavy. While some people have good results with a med/high compliance cart with a heavy arm, it's not recommended.
MM carts are harder than MC's to load properly. I really like the M20FL Super, but I had best results in med/light arms and loading with either high capacitance (400 - 500pF/47K) or 325pF/53K. Otherwise it can sound distant.
The cart sounds sluggish to me in an arm with mass of approx. 17g. My results suggest arm mass of 7 to 12g or so to be better.
MM's with lower compliance (w/high mass) are some of the Nagaoka, AT7V, and AT95/Clearaudio. The Nagaoka MP-200 is in your price range. The 200 has a boron cantilever and cu of approx. 16. The Nagaoka carts have a full bodied sound.
The AT7V has similar compliance and is usually perceived as more neutral sounding than some other AT MMs. It will be best with < 200pF. There's a lot of love out there for the MP200 and 7V, which is a bargain at < $200.
The AT95 and variants, and all the Clearaudio MMs have a cu of 15. You can get an AT95 with a Jico shibata for < $150, or use that stylus in any Clearaudio MM by cutting away the excess plastic stylus holder.
I was reluctant to recommend anything without knowing the specifics of the arm. If it is a high mass arm you might want to consider something like a Dynevector 10X-5, although I'm not recommending it. My experience with a 10X-4 was not good, but some people seem to like the 10X-5.
