Interesting in some add on scenery

I tried a VFR flight around my home vicinity. The default scenery is a joke, even citys are difficult to recognise.So I intend to get some add on scenery, and wan't some advice regarding what to choose.In the first place I'm interested in Europe and the vicinity around Gothenburgh (where I live), but even USA could be interesting since I fly there also.I'm interested in both individual airports and the whole Europe (and maybe parts of USA).I have found a lot of alternatives. One is a boxed version called 'European enhanced scenery' Abacus. According to the box at has been reviewed in avsim. But I find no such review or any other info about it on the net. Does anybody know more about it?Then there is FScene 2004. Somewhat expensive. Can I have both witout conficting with each other? I understand that they can enhance different aspects of the scenery.When it comes to scandinavian airports there several options with similar names that contains similar things.Performence issues are important. I use AS FS9 addonplanes and haveAthlon XP 2400+ 512M RAM and GeForce4 440 MX (plan to upgrade to Radeon 9800 Pro 128M)
