Dynavector Karat 17D3: retip for $500 or get something new?


I have a Dynavector Karat 17D3 cartridge which I liked soundwise until it began to mistrack severely. Had it examined and it turned out the diamond is almost completely worn out.

I can get it retipped with the new Micro Ridge Stylus for $500. Alternatively, I can attempt to sell it, add $500-$600 and get another cartridge. The question is: can anything it the range of $700-800  sound better than a retipped "old" Karat? 

My system consists of Mitsubishi LT-30 turntable, Nakamichi CA-7A preamp, SONY TA-N330 ES power amp and Solstice MLTL speakers. Speakers are not very bass-efficient so the new cartridge shouldn't be bright.

 taking the cartridge off and inspecting it under a microscope revealed that the diamond was displaced in the cantilever (in comparison to my 17d's) on this particular cantilever the diamond appeared to have been set into an open ended slot and that most of the diamond was sticking out of the back with hardly any of the tip showing.

This is my 17DS mkII under a macro lens, I have no idea how anyone can re-tip it, very bad idea! 
I post temporary links only, you are late. But what is the question? 
I just wanted to chime in, as a commenter in one of the relevant discussions linked to above. I had my Dynavector 17D (original) re-tipped by Joseph Long, and it sounds incredible.

If you're near KY and would like to see the craftsmanship in person and hear how it sounds on my setup, you are welcome to stop by. There's no amount of convincing I can do in a forum that would stand up to the impressive music it creates in my system. 

Joseph is on eBay as "cartridge_retipping-5". If he can retip an original 17D, he can retip a 17D3. Feel free to message me directly if you're looking for any more info on my experience or the result. 
@chakster , np. Just wanted to make sure you knew they had expired. It's why I post up links to Google Drive, so they can be accessed months/years later.
