It depends on how much you want to spend. There are very pricey guitars out there, but they also have such an high quality that you'll never find on a Gibson. PRS Tremonti or Singelcut, Knaggs Kenai, Frank Hartung guitars (Embrace), Seth Baccus Nautilus, Nik Huner Orca or Krautster II, Tom Anderson Bulldog....and many many others.
All of these are wonderful guitars, real works of art in most cases, but if you really want the Les Paul tone, you will have probably to go with a Les Paul!
If you have that sound in your head, probably all those guitar won't sound so good to you.
I have a PRS Tremonti, amazing guitar, very comfortable and fast neck, super high quality and great tone. It's built 1000 times better than a Les Paul, and every detail is really well done, but it does not sound like a Les Paul. I love PRS, but i have to go with my 2005 Les Paul standard to have THAT sound you're probably looking for.
But you live in the USA, you can find really a million used great LPs, and for a really nice price.
I personally will never buy a guitar with an auto o mini tuner, or with an ugly flag inlay on the fretboard saying "50" "60" "120" "2014" or anything else.
