Comparing MGA's / Aggregators - Your experience is welcome

[texasproducer]

I will mainly be doing personal lines and am looking to get under an MGA/Aggregator

Here is the list I have looked over so far:

Insurance Noodle
IAA Network
SIAA
Smart Choice
Superior Access
Agent Secure
Roamnet
Networked

If anyone has any experience these companies that would be great.
My main points of concern are:
1. Direct Access to Carriers with binding authority
2. Book Ownership
3. Product Availability in Texas
4. Commission Split

Other factors are the ability to transfer servicing to the mga, e&o coverage, possibility to transition into my own direct appointments, etc...

Networked (www.nlinksuite.com) seems to be mainly commercial since their PL carriers are pretty short in Texas.
