Quite by chance I came across a company in Hungary that offered DNA tests: Genodia. They concentrate on tests for various health issues (their English pages only list these), but reading the Hungarian pages one can learn that paternity tests and even other tests of relativity are on their service list, as well. I'm far from being well informed about these tests, but their prices seem to be a way too high when compared to FamilyTreeDNA or to GeneTree: a test of relativity level for 3-4 persons costs 200,000 Hungarian forints, which makes something like 900 US$.
