i had an Epiphone Les Paul for many years; wonderful thick humbucker tone; the Epiphone LP model was half the price and half the weight of the Gibson LP, but it was still very heavy (probably a factor in the thick tone). And it was also ergonomically weird, the body kept tilting downward.
so the Epiphone LP will save some $, but either Epi or Gibson models will be heavy and uncomfortable to hold.
that’s just my experience.
here’s my Epi LP with my acoustic Epiphones

What’s your price range? If you want a Gibson, I suggest that you get at least a Traditional Les Paul.

A Traditional Les Paul, in mint condition, just sold in my area (NorCal)for $1300. It sat at that price for a few days. The original asking was $1500. I almost bought it! 🙂

I’m in the market for a Standard myself. Right now, they’re going for around $2000 – $2200, which is still high in my opinion.

I can’t comment on what model years to look for since I don’t personally know. If the guitar appears to be in good condition for the price and I like it, I usually buy it.

Beware of fakes because they’re definitely out there!
