I have a Koetsu Goldline Black. Almost went for the Rosewood but someone familiar said the Black was awfully close. Whatever. Point is my Black is good enough I don't know what there'd be to replace it with for $1700. In other words even though that is a lot for a rebuild you probably wind up with a better cartridge than anything else you could do.
Rather than just send to Koetsu though I would at least make a phone call and ask Peter Ledermann the Soundsmith about it. He will probably be able to offer you options, some of which will make the Rosewood even better, save you some money, and for sure whether he says it or not will appreciate your business in these difficult times.
Oh, and his Zephyr MIMC is the one cart close to your $1700 that might just be better than your Rosewood. https://www.sound-smith.com/cartridges/fixed-coil/zephyr-mimc-☆ While saving you a lot of time going without. I would ask him about that too.
