They are pretty good but it all depends on the price you're paying.
I have a LS50 from early 1980 (reborn old). It's very heavy, but the overall quallity is nice.
Just remember they are one of the cheapest models of that year so don't put your expectations too high.
A friend of mine bought a 1979 Les Paul Reborn LS50 which is basically the same bones, similar weight and construction, just a 3-piece top instead of 2-piece, no fret nibs, etc. It too is a killer guitar.
I think you'll be happy if your offer is accepted.
I don't find anything amazing about them, or most of the MIJ LP copies, as much as I love Japanese goods in general. On the other hand, though, they're generally very good, sometimes excellent, and it's not as though Gibsons of that period, or Fenders for that matter, are (with some exceptions) anything special, either. But as long as you get a playable one, I don't think there needs to be anything extraordinaryt to dial in a guitar that fits you wonderfully. I rebuilt and re-equipped a very nice Orville, and while it was never going to be truly astonishing, it was better than most of the Gibson LPs I've run into. The only thing I dislike about Tokai's is the "Les Paul Reborn" crap. It's one thing to steal the design, but to actually us a person's name like that is damnable.
Just remember there was no old style 50´s les paul made by Gibson at the time so Tokai found a goal.
They did a really good job, these 79s are very good. I do love mine, played at high volume specially.
I don't have any pictures of it, but way back in 1997 I bought a Tokai Love Rock gold top here in Japan. I think it was a lower tier modal though (or perhaps had a defect) because I got it for about 60,000 yen. I sold it in 2006 and often think about buying another Love Rock (MIJ of course) but my Fujigen Cool Z ZLS-1 burst copy fills my LP Burst needs (for now )
