Do you know of a great real estate investment group in Austin?

Hi,

I would like to learn more about investing in real estate.  Do you know of any great investment groups in Austin?....and I'm not talking about the people who just want to sell you their books and tapes.  I would like to learn from other real estate agents who have been investing for a while, know what to look for, can share stories about common pitfalls, etc.  Thank you for your help!
