Here is just one source for a newly manufactured stylus:

Not a VR 1000. The Golden Classic and VR-22 look the same. My VR 22 has the model number on the body. I have one Golden Classic, one VR-22 and two VR 1000's. It is most likely a Golden Classic which was the first stereo model. The VR 1000 was the last and best GE model.
Hi Max. I probably had a Duotone 851d at some point. The only needles that I had any luck with on a volume basis were the VR 1000 needles made by Walco. There are two sellers of these on eBay at the moment. I have zero stock here. I have been out of VR 1000 needles for quite some time. I hope...
There are so many other sites that you can check:

lpgear.com
lptunes.com
eBay

Any of the 770's listed at The Voice of Music would work.
The 770-DET would be my choice. Some of the others are probably quite old.
TVOM shows a substitution:

A proper 606 type which would be MI, would not work but Switzerland (Synton) puts magnets on all of their mag needles so they will work in...
