Polar,
The yoke I use is the CH Products one at around £100 which is fine but if you want something with a more realistic metallic (rather than plastic) feel then check out PFC and AETI yokes which start around £400. Try
www.rcsimulations.com for info and prices Bob Sedgwick is very helpful.
Also check
www.avsim.com and
www.flightsim.com for free scenery and aircraft add-on's. If flying in the UK I strongly recommend the Barry Perfect GB Airports series and the Gary Summons UK2000 airports series.
I also fly for BAVirtual on VATSIM - the Simulated AIr Traffic Control network staffed by real and wannabee air traffic controllers and flying correct procedures - then it really is as real as it gets!
