EXTEAM S3 is quite normal, old files and have some bugs.
Reedlan (it’s exillum right?) have like mad bugs on it.
XG SIIX - really good files, have small bugs that can easily get fixed (not require a lot of time) but u don’t have src, so u may create ur own and hook it.
Have a look on the s3 files that FCV2005 released - they’re quite nice, have a cool features but have like ALOT of bugs. —> I’m working on them few months (bought it in 2014/5 and started working on it in the past year.
It has a lot of bugs, require a time (I’m in army so I don’t have much time to work on it. Only at weekend
)
in shortly:
hire a dev, take FCV2005 releases files (developer Dennis) and work on it
good luck!
