Thinking Of Buying CFS2.

I wanted to know what everybody thought of CFS2. The ups and downs. Should I buy it or should I skip it and get CFS3? Which is better CFS2 or 3? Also, I wanted to know about the mission editor with Cfs2. Do you still have to find the lat/long for each object you place in a mission like the old CFS1 add-on mission builders? Or can you place it with a map overview? (I've heard people say that the old Jane's games were like this) Basically I'm looking for suggestions on whether to buy CFS2 or buy CFS3 or just wait for CFS4.
