IFR Downunder?

G'day everyone, this looks like a really cool site. I was just wanting to know how easy it is to use FS 2004 for IFR missions in New Zealand and Australia. I tried a few using FS 2000 pro and became very frustrated because although I could plan a flight ok, when it came time to do the bussines, the navaids wouldn't come alive. I'm really just after something to help me start to get the process and patter going again for various local approaches etc. Will it do the job? Scenary is of secondary importance to me at this stage as I'll be more interested in what the clocks are telling me. I'd appreciate any comments from you guys before I spend the bucks on the software.
Cheers...
Pete.
