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

Yeah, that Jolida JD9II is a giant killer for the $$ and modest upgrades can make it even more untouchable. 
I just keep upgrading my Linn LP12--tomorrow I go to the Linn audio shop near me to have the Keel I ordered installed while I wait. I cannot afford both Keel and Radikal so doing just one for now. My Linn is about 15 years old and has Ekos II, Cirkus, Trampolin, Linto and Lingo 2, and an Akiva cartridge installed a couple of years ago. Every year or two I find I do something with my LP12. I heard the Keel demonstrated about 10 years ago at this shop and have never forgotten the mesmerizing sound that came out of a regular LP12. He had two tables ready for the demo, one with Keel and one without, and I was sold. But I couldn't afford the upgrade till now. I thought about doing something else, but the memory of how good that LP12 with the Keel sounded was still with me and I couldn't resist. I have not heard a before and after with the Radikal but reviews say it is a similar level of improvement. I am not one who typically can hear the difference between motors in audio components, so I'd like to have a demo before I splurge on the Radikal in the next year or two.
You should upgrade your Linn.  And play all your new disco and hair band vinyl.  It's a great match for your AR 2ax speakers.  Go out in the evening wearing your double knit leisure suit.  You can also finally upgrade your rotary phone to touch tone.
