Conflicting Info on this one.
P&E shows sales for Ron Laitsch, but Agent Verification shows no verifiable sales and has had complaints (they charge for photocopying as the expenses occur).
Also AC's site does not list their clients (often a bad sign) and promotes the fact that they are a Barnes & Noble Affiliate. B&N Affiliation has nothing to do with publishing or representation - it has to do with an affiliation with B&N's online store (a strange thing for an agency to promote).
On the other hand, Ron Laitsch is an AAR Member.
It appears that they are legit - but they don't have the greatest reputation. Check the Writer's Net discussion boards for more.
