I am using an realtor, but only to my benefit. Basically it goes like this for my realtor:
Hire him
Go out and find my new house and purchase.
Present him when you are buying at the closing.
He gives me 2% of the total 3% of his commission (claim taxes at end of year on my side).
I am happy with more $$ in my pocket as he gets a little something just to present him.
Simple and Easy.
My realtor tells me he gets a lot of bad calls and grips from other realtors for him doing this.
Realtors (most) suck anyways. Trust me as I known this from my last two home purchases. As long as you know what neighborhood, town, city you want to be in and you know where you want to be no need of a realtor to be present. They are there to make easy $$$'s for honestly not doing chit!

The buying power of not representing my realtor does no good as my new home builder does not give me any kind of incentive / discount if I did not present a realtor. So why not in my case. $4K free in my pocket.
