Have you looked at the line ups of Build Stuff in Vilnius? It has many of the same speakers as QCon, historically at a fraction of the price, and attendees from across Western Europe and the US. I have priced it out several years running, and with flights from major US cities or (especially) Europe, a hotel and expenses it is substantially cheaper than attending a US conference in the same tier. Disclaimer: I have worked on the CFP for that conference several times over there last few years, but have no financial interest in the conference.
