There are a ton of Falcon 4 add-ons, some official, some unofficial, so that's good. It probably isn't a waste of money.
On the other hand, LOMAC is newer. With LOMAC however, be careful which version you get since at least one LOMAC version had some destructive DRM that pretty much hacked your computer to replace the device drivers for all optical drives, and this can cause instability or even render your cd/dvd burners inoperable.
