Hey experts...closing in on a few used GC deals...rangng from gc2 to gc4. Various conditions etc. in GENRAL...."general"....are there tons of problems with these tables, or for the right price its worth it and can be fixed by a good mechanic? Ones in great condition are $$$$, but ones 10years old never been moved not so $$ I know nee cwoth, new cushions are a general need...but are they generally easy to fix if need work past that...AKA...are they costly to get playing right...not talking abut refinishing. Thanks.
