What is a reasonable cost for a CPA?

[Johann Jells]

My wife hates our CPA. We don't get much advice, he's disorganized, and the last straw was him sending out a group email to 200+ clients exposing everyone's contacts! That's like a 1998 internet mistake. I would never do that to my tenants! But he's apparently inexpensive. 

Our taxes ARE a bit more complex than average, 2 schedule C's in addition to an LLC holding our 3 properties, filing as an S, no recent schedule A since the standard deduction was raised. But I used to do it myself using Turbotax prior to the LLC. I feel like we're paying simply for data entry.

So what's reasonable? Being in the NY Metro we know it's more than some areas, but we got a price from a referred CPA in Minneapolis, and they were way more expensive!
