Hi Simon,
to IIS and as madtuna says, you'll get plenty of help here.
You'll find your choices very limited if you stick to WA suppliers - and I mean LIMITED
So I've shopped over east except for a 2nd hand etx that I bought from another iis'er in Perth. You will be stuck with shipping if something should go wrong, but generally speaking I'd say things don't go wrong that often that would necessitate sending it back. For me, the risk is worth it. Happy hunting
Cheers,
