I've owned 4 Foderas up to this moment and I've kept the two (have played another 3 Foderas, as well). It all boils down to what you think it's worth.
Good materials and construction, good attention to the details, ergonomics are closer to the "old school" side (wide neck and bridge string spacing; not my fave really) but the tone is something very personal and subjective. My R-bass was on par with with the best Foderas I've tried, for a fraction of the price; resale value for the R-bass was not as good, if one bought it brand new. If one person cannot hear the difference between a specific Fodera and another specific bass, then it's not worth to even try to acquire it (no need to generalize, unless one has extensive informed knowledge from personal experience, but even then...). If one person can hear a considerable difference, then by all means it's worth.
