might depend some upon area, here a snooker table isn't worth much because of the real estate values pushig them out of the city. sure a GC or a real vintage table may have value. It may be different in a lower rent area where pool halls can survive over developer's interests.
from what I can see these makers seem to make imitations of old tables with particleboard parts, laminates, etc. I'm not sure how far they might date back.
some have money and buy new tables in the thousands while sharper budget minded find better ones for free. These types often arent' very price conscious, because they are well off , they just order new stuff and to them 30K is nothing.
moving them can be expensive if you need to hire a mechanic and some guys to carry slates or even machinery. I see a lot of used ones listed by dealers with the price including the move , levelling, cloth installation etc included.. Even if you pick up a used one for free you need to deal with moving and installing.
Id call around to any local mechanics and suppliers, maybe they can sell them from pictures and move when sold? Tables in pieces dont display well but if it's a really good table it will be recognised as what it is.
If you disassemble, you might think to get lots of good pics first because you might have it in a disassembled state for a while.
You might post them in for sale, put in your area, maybe a local will find it that way. I suspect no one will want to ship them too far. the area and value are related.
