Best Broker in Texas for Real Estate Investor

[Jeff Jenkins]

I just recently passed my agent's exam and am looking for a sponsoring broker. The thing is that I only intend to do this part-time, mostly for personal investing, and I'm trying the find the best broker (financially) for my needs. I just met with Keller Williams, which seems like a great fit for a full-time agent, but for me their monthly costs would render it a counter-productive partnership.

Anyone have any suggestions? The key is minimal costs. I'm not concerned about paying more in commission.
