I need some turntable guidance

Elizabeth is spot on
Spinning records is not a media of convenience.
It takes a degree of enthusiasm and dedication.
Then after all that IF you went the cheap table and cart route you may well find yourself wondering what all the fuss is about as you most certainly will be underwhelmed at the sq.

Put simply , you will likely need to spend a fair bit more on a vinyl setup to achieve SQ that compares with a modest outlay on a digital setup.

The TT itself, the cartridge, the phono preamp, cables, SUT, record cleaning system.
All things you will look at and possibly spend money on down the vinyl rabbit hole.
You pays your money and you takes your chances.....

Btw OP.
Please do not get the impression that anybody is trying to put you off.
Rather just make you fully aware of some of the downsides and what is involved to be SATISFIED with record playback.

I currently have a turntable but want to upgrade significantly.
I want a new one or at least a recent one.
I have a record collection.
I don't have a budget. I know where a supposed good deal is on a demo turntable for $10k. One of my questions is should I spend that kind of money or say are the differences marginal or great from a $5k to spending $10k? What do you get when you go up in price? Or what do you lose going down? Where is the sweet spot in higher end turntables? I think something matching to my system is where I should be but what price range would that be? 

I don't follow audio gear so I really am not aware of what my options are. There are no dealers in my town.

Maybe you could have opened with that information?
Lol.

A lot more there for members here to now go to town.
