I believe the issue is that VSL only covers the licenses on the keys for 2 years, so if they go after that (get zapped, are unrecognized, or just die) you'd have to buy the instruments all over again. I think the idea is if they buy a new key and transfer their licenses to it every 2 years, the licenses remain "insured" against the key dying (they allow you to download them again). Now I don't know if this has been changed recently, as it has always been met by complaints. I also have never bought a VSL instrument (besides the free ones that come with VE Pro) for this very reason. Since I've seen iLoks get zapped in the past and need replacement, I'm thankful iLok will replace all your licenses up to once a year if you lose them (I'm sure an email explaining could work if you have it happen twice). But VSL, perhaps until recently, has always taken a hard line against replacing lost licenses, regardless of how it happened. For me (unless this has changed) is a bigger deal than price or even how good it sounds, if it means I'm paying $450 that I may have to pay again someday. You can get almost any other piano for that price these days. For me the potential hassle and frustration is not worth it.
