Those have a lot of fans. As you have played it and found it to be worthy, I think you may already have your answer. Ttops were on late 60's to early 80's and were not available on the Classic from that time which came stock with high output ceramic magnet loaded, exposed black coils, (coverless), 500T and 496R humbuckers. So, pickups are not original to the guitar. How important that may be is your call.
A 2000 Classic gold top was my first Les Paul, read review here.. I love my Classic! Quality was outstanding, and has remained so over ~20 years. There's nothing like you're first...
-- 1600 Pounds Sterling seems to be the nominal market price, slightly more or less, depending upon condition.
-- 1200 seems to be a deal, especially if this one ticks your boxes and you are bonding!
Per Al, ceramics are the norm and stock will give you latter Classic Rock tones. Don't know how T-Tops would sound in these guitars. But at that price, seems you could tweak and mod if you didn't like it.
