I'd personally say if you have any use for one of the Spirit upgrades (which is pretty likely, since they're super cheap sources of CDR and the stat of your choice), go for it. Otherwise I probably wouldn't bother. Keep in mind that you get part of the money from Philo back, while for Spirit stone you don't.
