Decision made.

Thanks everyone for their replies.

Both Ensign and IR/T do the job I want, and like Reaver said the support, upgrades, responsiveness from BOTH is just OUTSTANDING. Deciding between the two was almost down to the toss of a coin; I went with IR/T.

Gone are the days when making a decision like this was an expensive one to get wrong, spending $1000 or whatever on a charting package, each of these are about $US40 a month for what I want (plus the gouge from the data supplier of course - wounded bulls aint in it). If, for some reason I want to change over to another charting package the process is painless and $ cost-free.
