Tonearm for Luxman PD 441


I have a late 70's Luxman PD 441 turntable with a Grado The Reference high output cartridge that I really like.  I'm thinking that my weak link is the old Denon DA 307 tonearm with that goofy rubber for damping.  Any suggestions on an easy switch for under $1,000, even used?  Thanks all.

Fidelity Research FR-64 had the same 230mm mounting distance , is a drop in replacement of the DA307.
I have a PD-441 with a Fidelity Research FR64s, the optional vertical height adjuster, and a Yamaha MC-1s moving coil cartridge. It is my second-tier table, but I am very pleased with (and actually surprised at) how good these pieces sound together, plus they look absolutely fantastic.
Seems like the Fidelity Research FR 54 is a lot less expensive to buy than FR 64.  Is there much of a difference?  They both seem to be same dimensions, so should work with my PD 441
Could you not just get a local woodworker/vinyl enthusiast to make a tonearm board for you? That's what I do. Usually around 100 to 200 bucks
regarding a tonearm board, I'm not sure how I would attach it to the table.  The spot where the tonearm would attach normally is on a sliding track, so there is seemingly quite a bit of adjustment available to get closer or farther away from the spindle.
