I am in similar situation, though not with a LP12 or at your budget. I am with those who have encouraged you to refurbish your table, with possibly minor upgrades and listening to it for a while to get a sonic ‘feel' for it again. Your table would likely be worth the funds you have put into it when finished, and if your then decided to purchase a different table it could be sold to help fund this purchase. Though I would’t sell it until I had compared to the new table, if only for my own edification. More importantly, you might find the refurbished LP12 might be the only one you need.
Regarding the Jolida phono, I once owned one and while it is very good at its’ price point, you could do better. A decision that could be made after the TT decision.
