While it's still available, it really hasn't been updated for FS-X.
It's still a viable program.
More important that those programs, though, is that the serious panel designer/builder should be familiar with the Panel/Gauges SDK   After all, when building a panel, there is nothing the the programs do that can't be done with a text editor ...   the programs just make it soooo much easier.
