Newbie here - need help regarding t-table upgrade

I'd like some opinions regarding my old turntable.
I have a Thorens TD 318 that I bought in the mid-80s.
I haven't used it much since digital took over. However, I've
decided that my vinyl can still be a great source of enjoyment so
why not dedicate some time and money to make it the experience
the best that I can. I don't have a lot of funds and would like to
be as thrifty as possible. My question is - is this particular model
one that I should simply have cleaned up or should I go with something
new? If new, what suggestions would you make for between 600 - 800.00?
Thanks for you help.
