I have a ’89 les paul standard, and a ’98 SG standard, they both sound very different, they play very different too, they are both absolutly fantastic instruments, but the one i play most is the SG, it has such a tone variation between the 2 pickups, always puts a smile on my face when i play it, go for the SG, dont know about build quality, but if i was you i’d save the money and go for a good used one.
