Happy New Year!

I'm a new member; I came here recommended by one of your casuals, and I am already getting a lot of good info reading past posts, so thanks for having me. I am looking forward to meeting other guitar lovers like me!
My New Year resolution is that in 2024, I will buy my first Gibson Les Paul Custom Black Beauty, ideally from the 90s, as I don't know if I can afford a 70s one, and will become my new partner in crime for years to come. I am a huge John Sykes fan, and I have played borrowed LPCs over the years but never managed to get my own. I have been living with a Flying V and a Charvel Socal for the past ten years.
One of the members let me borrow his 80s LPC, making me want my own even more!
I am after advice on how to find the perfect one for me in terms of Specs, years, what to look after, where to look, any leads, what years had good woods, which to avoid, etc. I don't know much about the whole hardware and gear, so this is the best place to learn this side of guitars I've always ignored.

Thanks so much for having me, and your help is very appreciated!
