Reviewing Van's pricing online shows a YIO-360-A1B6 (200Hp 4 cylinder) at $48,650.
The UL 520iS (200hp, 6 cylinder) is currently at about $41k, but can vary with Euro exchange rates. However, that 41k includes FADEC ignition and injection, baffling, alternator and the exhaust system, which the Lycoming does not, so the price gap is really quite a bit greater. If you're feeling froggy, you can get the 520 Turbo for about $10k more, but I suspect the safety police will come along and naysay that idea quickly noting the inability of pilots to actually control the black knob at speed. {heartfelt sarcasm}
