I have no use for one.
If it is worth owning depends on what kind of stuff you like and what you plan on doing with it.
As an expample I have a Sun Ultra 5 machine which many people view as a generic PC'ified SUN because it uses IDE and has a common ATI Rage video chip (VGA not 13w3) instead of something exotic. For me it is great because of the size, the fact I can use a generic VGA monitor with no expensive adapters, and I have plenty of IDE drives. Since I won't be using it to compile software the IDE interface is not an issue (SCSI would be better for that task). So a SUN road Apple is just what I needed for dabbling with Solaris, others would want a more highend SUN.
