Weird, this page didn't load fully but I think I can still respond.
Anyway a Cetme is sort of the earlier version of the german G3 battle rifle made in Spain (where the rain falls mainly--nevermind). Unfortunately to comply with import laws Cetmes are basically assembled, sometimes not terribly well, by Century International Arms. Plenty of guys have gotten good ones out of the box, but others have had to futz with the gun to get it working. If you are able to work on guns, or are willing to take a gamble and not be really upset if the rifle has issues, there is nothing wrong with a Cetme.
The FAL is a different design .308 battle rifle. From a military standpoint it is a similar rifle in the role that it plays, but it is a different design. Gunnutz will (and have) argued the relative merits of the g3 v. FAL to death almost as badly as 9mm v. 45. I think FALs are more popular partially because between assembled guns from DSA, guns built on parts kits by other gunsmiths and the ability to build them at home from parts kits, they have been more readily available.
