The MMC20CL in good shape is worth more than $200, alone.
It can be re-tipped for much less than $650, if and when needed. There are others in the re-tip business besides Sound Smith.
Buconero, Unless I am mistaken, the Shure 97 is not a P mount type, and the tonearm on the Beogram accepts P mount cartridges only. (But perhaps there is an adapter for standard mount cartridges; I wouldn't know.) However, there are a lot of P mount cartridges out there to choose from, push comes to shove, some of them cheap and good.
In summary, no one knows why eBay auctions are all over the place, and you should not care. If your turntable works. well and if the cartridge is in good shape, you did very well.
