It all comes down to how valualble time is to you. If you have 10-30 min a night to check a bunch of places to verify who to start then you probably don't need goaliepost. However, if you don't have that much time/intrest to put into finding each teams starter and still want to be competitive $10 is well worth your time.
If you're league/team is competitive then one missed goalie start could lose you a week, which could come back to bite you in the ass later.
