Hi,
I've done my SACAA to UKCAA convex a few years back in Bristol, UK. ATPL distance learning package/groundschool with bristol.gs, then the flying part with Bristol Aviation. Was expensive, but well worth it. Excellent team.
Should be cheaper in Eastern Europe though. Check out Malev Aero Club, CAVOK and Pannon Air in Hungary as well as Lets Fly in the Czech Rep.
