Upgrade Linn LP 12 or buy new table

I would like to get back into vinyl after an approx. 17 year absence. I have a Linn LP 12 that I bought in 1983 which I used for 15 years and then put into storage. I never got rid of my vinyl. So my question is : Do I upgrade my LP 12 to the tune of three to four thousand dollars or do I spend the same amount on a new turntable and sell the LP 12?  Everyone's two cents worth would be greatly appreciated.  Thanks
