I'm an Edge 540 person myself, although the IRIS Christen Eagle is nice too.... Edge 540 (the FS2004 one, if you remove the rollrate 'limiter' from the panel cfg, FSX does not have this issue, but overall the rollrate is a bit faster than the Extra) you can also choose from 2 models, with race tips from without, on without model click the left diagonal cockpit brace and the wingtip sighting fences are hidden, in FSX click the right diagonal cockpit support and the GPS gets fixed there... can't tell i love the Zivko Edge 540... my signature gives it away a bit...
