I considered safelog when I was looking at the options, but it seemed to be quite expensive for what it was offering.
After the advice I received from asking on here and friends at work, I went for MCC Pilot Log.
As already said its a great piece of software, only a one off payment (69 Euro) unlike safelog (think every 3 years you license fee, but I can't remember 100%), I can also import everything from my airlines online roster. So all I do is press a button and import all my flying hours.
Hope someone can give you some practical advise about Safelog, but I definately recommend MCC.
Hope this helps
