Thanks for all the advice and replies guys! The 3 Hotas i posted are not only based on price but also availability. Unfortunately CH products are quite expensive in Australia and also hard to find, particularly the throttles.
I do see myself getting immersed in this game, I absolutely love car simulators and this is probably the next evolution. I use my steering wheel at least a couple of times a week. Perhaps this will be my next over used peripheral.
I think i will go with Pyro's suggestion and get the X52 Pro and the foot pedals. Then if I get totally addicted, sell it on ebay and get the Warthog Hotas.
My only concern about the x52 over the Warthog is how hard is it to configure, but I believe there are downloadable profiles.
After looking into Tracking IR, flight 'simming' looks like a very expensive hobby:doh:
