Hi Mike,
I currently use Just Flights Traffic and their further add ons like the military traffic and commuter traffic which are available from their web site to download about £7 each and dont need the main package to use them, ( I find this a good poduct provide plenty of traffic during flights on approach and at airports but does require a little tweaking after installation so not to get go-arounds every time) but i have also just seen MY Traffic X which is available for FS9/FSX whichi fancy giving a go.
