Since your from Belgium, your best at getting the things graded at UKG to save some shipping costs, i think they almost are as known as AFA now.
But, AFA is still the better known global service and i still think higher of figures graded by AFA then figures graded by UKG, also for rarer loose figures for example Lili Ledy Bib Fortuna, Uzay Darth Vader, Toltoys VC Jawa, Top Toys Luke Jedi etc... or rarer carded figures like Uzay, i think your still better off at AFA for authentication.
