I have the same table. I would make sure I had the BEST phonostage I could afford and go up a level with the LOMC.
The Classic is worthy of a more upscale cart than the Benz Ace.
I have used a Benz Glider, Sumiko Blackbird and Audio Technica OC9III/ART 9. To my ears, in my system, the ART9 is a winner.
The ART9 has remained on my table for over a year.
If you get maximum resale and only have to cough up the difference for the Prime, it may be a good move.
I still would seriously consider phono stage/LOMC.
