Laurie,
RANT 3.1 (i.e.the previous version) is also very good and has the advantage of coming with an instruction booklet which goes through the product step by step. I find this much easier to use than the on-disk help index that is all you get with RANT 2000. I still refer to my 3.1 instruction book to find out how to do things with RANT 2000. If Oddsoft are at the Flight Training Exhibition they usually have an offer which is about £10 off. Thats how I bought my copies. I have a feeling that there is a free demo that you can download from their website, but I have an urgent (alcoholic) appointment down the road and haven't time to check right now.
